By accounting for the coupling between the quantum CNT and the classical electrolyte-filled pore capacitances, we study the case where a gate voltage is applied to the CNT. The computed surface charge and conductivity dependence on reservoir salt concentration and gate voltage are intimately connected to the CNT electronic density of states. This approach provides key insight into why metallic CNTs have larger conductivities than semiconducting ones. Introduction Although much experimental, theoretical, and molecular modeling effort has been devoted over the past years to understanding water and ion (electrolyte) transport through carbon nanotubes (CNTs) [1–3], the origin of the electric charge localized on the surface of industrially important CNT based nanofluidic systems still remains unclear (see Ref. [4] and references therein). It has already been proposed that this surface charge could arise from functional groups at the CNT entrances [5, 6] and/or the specific adsorption of ions, such as OH− [7]. Although the above cited studies lead to the conclusion that this surface charge plays a key role in governing ion transport in CNTs, it is difficult to regulate it directly and one is left to making inferences, for example by studying the variation of ionic conductance G with the pH or salt concentration, cs, of the external bulk reservoirs bounding the CNT. Intriguing results have been obtained, including a power law behavior, G ∝ c α s , with 1/2 ≤ α ≤ 1, which could be interpreted as the manifestation of an underlying surface charge regulation mechanism [8–10]. Through a simplified feasibility study we propose in this work that by biasing a CNT incorporated in a nanofluidic system via an applied gate voltage, Vg, and taking into account explicitly the quantum capacitance (QC) of the quasi-1D CNT structure as well as the nonlinear capacitance of the confined electrolyte ion the pore, it should be possible to quantify the CNT surface charge density σQ and establish a link between the intrinsic CNT electronic properties and ion transport through the same structure, such as the electrolyte conductance through the CNT. A major conclusion it that these intrinsic electronic properties will depend significantly, under certain conditions, on whether the CNT is metallic (M) or semiconducting (SC). Conclusion As an concluding example, we consider the experimental results obtained by Liu et al. [30], who measured, for cs = 1 mol/L, conductances of 61.0 nS for M SWCNTs and 5.6 nS for SC ones with 0.8 ≤ d ≤ 2 nm and 5 ≤ L ≤ 10 nm. Using the DOS given in Fig. 1(a) with d = 1.5 nm and L = 8 nm, we can account for these two conductance values by taking Vg ≃ 0.35 V, a value that we interpret as an environmentally induced shift in the zero of the gate tension. More systematic experiments are clearly needed to ascertain to what extent the charge density and therefore the electrolyte conductivity through SWCNTs can be controlled by an applied gate voltage. Presumably, a more complete model for conductivity would be needed to account for the full complexity of real CNTs, including the influence of pH (via charge regulation), residual geometrical capacitances, and dielectric interactions.

Buy Unlock us Newsletters Abstract The application of machine learning models in quantum information theory has surged in recent years, driven by the recognition of entanglement and quantum states, which are the essence of this field. However, most of these studies rely on existing prefabricated models, leading to inadequate accuracy. This work aims to bridge this gap by introducing a custom deep convolutional neural network (CNN) model explicitly tailored to quantum systems. Our proposed CNN model, the so-called SpookyNet, effectively overcomes the challenge of handling complex numbers data inherent to quantum systems and achieves an accuracy of 98.5%. Developing this custom model enhances our ability to analyze and understand quantum states. However, first and foremost, quantum states should be classified more precisely to examine fully and partially entangled states, which is one of the cases we are currently studying. As machine learning and quantum information theory are integrated into quantum systems analysis, various perspectives, and approaches emerge, paving the way for innovative insights and breakthroughs in this field. Introduction In quantum mechanics, an extraordinary phenomenon known as quantum entanglement arises when two or more particles interact so that their quantum states become related [1]. This relation indicates that the particles become correlated and can no longer be described independently [2]. Any change made to one particle will be instantaneously reflected in the others, even if they are far apart [3]. Creating and increasing entanglement in arbitrary qubits for quantum algorithms and quantum information (QI) theory protocols, in which entanglement is a vital resource, plays an influential role [4]. As proof, it excludes undesirable energy levels in quantum annealing [5] and facilitates the exchange of quantum information over long distances [6]. It also provides conditions for transferring classical bits of information with fewer qubits [7]. The first step in creating and increasing entanglement is recognizing its existence and amount. In recent years, various entanglement detection criteria have been proposed [8]. Yet, the positive partial transpose (PPT) criterion determines entanglement only in 2⊗2 and 2⊗3 non-mixed bi-party states by indicating the state is separable if the partial transpose of the density matrix is positive semi-definite [9]. In other words, there are some mixed states that are entangled but still meet the PPT conditions, which are called bound entangled states, as they cannot be used to create a maximally entangled state through local operations and classical communication (LOCC), even though the reduction criterion has been practical here [10]. Moreover, Werner states are another instance in which PPT is violated [11].

One significant hurdle is applying artificial intelligence (AI) to this field due to the complexity of feeding data with complex numbers into conventional AI models. However, this article presents a groundbreaking solution that addresses this challenge and propels the field forward. The key contribution of this research is the development of an advanced deep Convolutional Neural Network (CNN) model, boasting an impressive accuracy rate of 98.5%. This innovative model successfully overcomes the limitations of handling data with complex numbers, thereby unlocking new possibilities for effectively leveraging advanced machine learning techniques in processing quantum information.

Buy Unlock us Newsletters Abstract Gravitational lensing studies of the Bullet Cluster suggested convincingly in favour of the existence of dark matter. However, it was performed without the knowledge of the original orientation of each galaxy before gravitational lensing. A potential improvement to this issue lies in the measurement of the original orientation from the polarization direction of radio waves emitted from each galaxy. In this context, Francfort et al. derived a formula that can utilize the information about the original orientation of each galaxy to obtain what is called shear. However, we demonstrate that shear in their formula should be replaced by reduced shear when the change in sizes of images of galaxies is taken into account. As the previous gravitational lensing analysis of the Bullet Cluster used reduced shear, we suggest applying our improved formula directly for the reanalysis once we obtain the polarization direction of radio waves. In particular, we show that our new formula can yield a more accurate analysis than the previous one, if the polarization direction can be measured more precisely than 10◦. To read the full article please purchase. Introduction There are many observational results that favor the existence of dark matter. One of the most convincing results is the gravitational lensing analysis of the Bullet Cluster [1]; matter present in the Bullet Cluster, be it baryonic matter or dark matter, distorts the images of galaxies behind the Bullet Cluster, by its gravitation. The authors of Ref. [1] analyzed such images to reconstruct the mass distribution at the Bullet Cluster, which did not coincide with the baryonic matter distribution obtained by X-ray image. Thus, they concluded that dark matter is responsible for the discrepancy. In order to analyze the gravitational lensing effect, certain assumptions about the original images are necessary since the observed images of galaxies alone cannot determine the distortion. In Ref. [1], it is assumed that the average orientation of the original galactic images in each small patch of sky, where variables related to gravitational lensing are determined, is zero. However, this can lead to errors if there are not enough galaxies in each patch. Although this represents the optimal approach based on the currently available observational data, the analysis requires a sufficient number of galaxies to statistically determine the gravitational lensing effect in each patch. Otherwise, accidental skewing of the original galactic orientations could lead to skewed results. However, it is now possible to determine the original orientation of galaxies from the polarization of the radio waves from each galaxy. The radio emission from each galaxy is known to have a polarization that is perpendicular to the major axis of its ellipticity [2, 3]. While the orientation of a galactic image is rotated by gravitation, polarization is not. Therefore, even if the average original galactic orientations were distorted in a certain direction by accident, possibly due to the small number of galaxies in each small patch of sky, it would not bias the data, as long as we know the original orientation and therefore are able to compensate it. Thus, we can use this information to our advantage to measure the lensing effect more accurately, as pointed out in Refs. [3–5]. Therefore, the position of dark matter at the Bullet Cluster may be corrected if we reanalyze the gravitational lensing effect with the help of the polarization data of radio waves, which would be available in the future [6–8].

For example, interlayer excitons in two-dimensional transition metal dichalcogenides show intriguing optical properties at low temperatures. Here we report on room-temperature observation of interface excitons in mixed-dimensional heterostructures consisting of two-dimensional tungsten diselenide and one-dimensional carbon nanotubes. Bright emission peaks originating from the interface are identified, spanning a broad energy range within the telecommunication wavelengths. The effect of band alignment is investigated by systematically varying the nanotube bandgap, and we assign the new peaks to interface excitons as they only appear in type-II heterostructures. Room-temperature localization of low-energy interface excitons is indicated by extended lifetimes as well as small excitation saturation powers, and photon correlation measurements confirm single-photon emission. With mixed-dimensional van der Waals heterostructures where band alignment can be engineered, new opportunities for quantum photonics are envisioned. Introduction The discovery of van der Waals (vdW) materials, including two-dimensional (2D) transition metal dichalcogenides (TMDs) and graphene, has brought about a revolution in the assembly of artificial heterostructures by allowing for the combination of two different materials without the constraints of lattice matching. Such an unprecedented level of flexibility in heterostructure design has led to the emergence of novel properties not seen in individual materials. A prime example is twisted bilayer graphene at magic angles, which exhibits exotic phases such as correlated insulating states [1] and superconductivity [2]. Another notable development is the stacking of two TMDs, resulting in the observation of unique excitons known as interlayer excitons, characterized by electrons and holes located in separate layers [3–6]. The spatially indirect nature of interlayer excitons imparts them with distinct properties, including long exciton lifetimes [3], extended diffusion lengths [7], large valley polarization [8], and significant modulation by moir´e potentials [9, 10]. The existing vdW heterostructures comprise of 2D materials with similar lattice structure, excitonic characteristics, and inherently identical dimensions. Development of vdW heterostructures that encompass lower dimen- sional materials may give rise to unique interface exciton states resulting from the mixed dimensionality. Carbon nanotubes (CNTs), a typical one-dimensional (1D) material, are ideal for such heterostructures as they have all bonds confined to the tube itself [11, 12]. CNTs interact with 2D materials through weak vdW forces, resulting in well-defined, atomically sharp interfaces [13, 14]. The chirality-dependent bandgap of CNTs can be utilized to tune the band alignment [15], allowing for unambiguous identification of excitonic states at the 1D-2D interface. Conclusion Air-suspended carbon nanotubes. We prepare airsuspended CNTs using trenched SiO2/Si substrates [11]. First, we pattern alignment markers and trenches with lengths of 900 µm and widths ranging from 0.5 to 3.0 µm onto the Si substrates using electron-beam lithography, followed by dry etching. We then thermally oxidize the substrate to form a SiO2 film, with a thickness ranging from 60 to 70 nm. Another electron-beam lithography process is used to define catalyst regions along the edges of the trenches. A 1.5 ˚A thick iron (Fe) film is deposited as a catalyst for CNT growth using an electron beam evaporator. CNTs are synthesized by alcohol chemical vapor deposition at 800◦C for 1 minute. The Fe film thickness is optimized to control the yield for preparing isolated CNTs. We select isolated, fully suspended chirality-identified CNTs with lengths ranging from 0.5 to 2.0 µm to form the heterostructures with WSe2. Anthracene crystal growth. For transferring WSe2 flakes onto CNTs, we grow anthracene crystals through an in-air sublimation process [17, 18]. Anthracene powder is heated to 80◦C on a glass slide, while another glass slide is placed 1 mm above the anthracene source. Thin and large-area single crystals are then grown on the glass surface. To promote the growth of large-area single crystals, we pattern the glass slides using ink from commercial markers. The typical growth time for anthracene crystals is 10 hours. Transfer of WSe2 by anthracene crystals. First, WSe2 (HQ graphene) flakes are prepared on 90-nm-thick SiO2/Si substrates using mechanical exfoliation, and the layer number is determined by optical contrast. An anthracene single crystal is picked up with a glasssupported PDMS sheet to form an anthracene/PDMS stamp. Next, the WSe2 flakes are picked up by pressing the anthracene/PDMS stamp against a substrate with the target WSe2 flakes. The stamp is quickly separated (> 10 mm/s) to ensure that the anthracene crystal remains attached Reference [1] Y. Cao, V. Fatemi, A. Demir, S. Fang, S. L. Tomarken, J. Y. Luo, J. D.

Buy Unlock us Newsletters Abstract Holmberg II – a dwarf galaxy in the nearby M81 group – is a very informative source of distribution of gas and dust in the interstellar discs. High-resolution observations in the infrared (IR) allows us to distinguish isolated star-forming regions, photodissociation (PDR) and HII regions, remnants of supernovae (SNe) explosions and, as such, can provide information about more relevant physical processes. In this paper we analyse dust emission in the wavelength range 4.5 to 160 𝜇m using the data from IR space observatories at 27 different locations across the galaxy. We observe that the derived spectra can be represented by multiple dust populations with different temperatures, which are found to be independent of their locations in the galaxy. By comparing the dust temperatures with the far ultraviolet (FUV) intensities observed by the UVIT instrument onboard AstroSat, we find that for locations showing a 100 𝜇m peak, the temperature of cold (20 to 30 K) dust grains show a dependence on the FUV intensities, while such a dependence is not observed for the other locations. We believe that the approach described here can be a good tool in revealing different dust populations in other nearby galaxies with available high spatial resolution data. Introduction Dwarfs galaxies (DG) – galaxies with baryonic mass of 𝑀𝑏∼109𝑀⊙, are commonly thought to be the building blocks for the entire hierarchy of mass distribution in the Universe, being progressed during its evolution since post-recombination epochs through merging process (White & Rees 1978). Within this concept, DG in local Universe can serve as laboratories for understanding the details of physical processes regulating formation of the very first galaxies in early Universe (see review by Tolstoy et al. 2009, and more recent discussions in Henkel et al. (2022); Annibali & Tosi (2022)). Among the most important traits of DGs are their metal-poor interstellar medium (ISM) and, correspondingly, a low dust content (Henkel et al. 2022) – the features that are also commonly expected for early Universe galaxies. Observations of bright galaxies at 𝑧 > 10 conducted first by the Hubble Space Telescope (HST), and subsequently by the James Webb Space Telescope (JWST), have indeed indicated a deficient amount of dust in a set of high-𝑧 galaxies (see discussion in Finkelstein et al. 2022; Ferrara et al. 2023). In order for local DGs to indeed provide relevant information for understanding of their more distant congeners, the comparative analysis of their global emission characteristics, along with the respective properties on smaller scales, is of a high importance (relevant discussion can be found in Izotov et al. 2021; Henkel et al. 2022). A good example of a DG in local Universe is the Holmberg II (Ho II) galaxy belonging to the nearby M81 group at a distance of ≃ 3.4 Mpc. Its modest inclination angle (≈27◦ ; Sánchez-Salcedo et al. (2014)) makes Ho II a very informative source of distribution of gas and dust in the interstellar discs. Spitzer and Herschel space telescopes with the angular resolution of ∼ 2 ′′ − 5 ′′ can probe the Ho II interstellar disc with a high scrutiny. Scanning the interstellar medium (ISM) with such resolution can allow to distinguish isolated star forming regions (SFR), photodissociation (PDR) and HII regions, supernovae remnants, and can provide information about relevant physical processes. In this Letter we analyze spectra of dust emission in the range 𝜆𝜆 = 4.5, . . . 160 𝜇m from Spitzer and Herschel archival data, focusing on a few rather small-area locations. It allows us to distinguish IR emission which cannot be attributed to the isothermal dust, thus requiring existence of at least two populations of dust with different temperatures.Since the primary source of dust heating is the absorption of UV/optical photons by the dust grains, we have also utilised the highest available resolution (1.2 ′′ −1.6 ′′) FUV observations of Ho II galaxy obtained by the UVIT instrument of India’s AstroSat mission (Singh et al. 2014) as part of this study. The data correspond to 3 epochs in 2016, 2 epochs in 2019, and 3 epochs in 2020 (Vinokurov et al. 2022). These observations are crucial in understanding the UV radiation fields, responsible for modifying the dust populations and © their thermal IR emission profiles at these locations.

(ii) In several locations, connected to physically distinct regions, we found spectra that can represent several – up to five, dust populations with different temperatures. Spectral characteristics are not sensitive to the HI column density, except for the cold dust component with 𝑇𝑑 = 10 − 15 K which concentrates predominantly in HI deficient regions. Preliminary inspection shows that this cold dust population does not show a dependence on FUV intensity. (iii) Similarly, the cold dust in those regions with spectra peaking at 70 𝜇m has temperatures nearly in the same range as the HI voids with little dependence on FUV intensity. However, for those locations with the peak intensity at 100 𝜇m, the temperature of the cold dust component (𝑇𝑑 = 20 − 30 K) increases with FUV intensity. (iv) The estimated dust mass manifests signs of anti-correlation with its temperature, as formerly reported for dwarf star-forming galaxies by Izotov et al. (2014).

Buy Unlock us Newsletters Abstract We study the effect of asymmetric fermionic dark matter (DM) on the thermal evolution of neutron stars (NSs). No interaction between DM and baryonic matter is assumed, except the gravitational one. Using the two-fluid formalism, we show that DM accumulated in the core of a star pulls inwards the outer baryonic layers of the star, increasing the baryonic density in the NS core. As a result, it significantly affects the star’s thermal evolution by triggering an early onset of the dir ect Urca process and modifying the photon emission from the surface caused by the decrease of the radius. Thus, due to the gravitational pull of DM, the direct Urca process becomes kinematically allowed for stars with lower masses. Based on these results, we discuss the importance of NS observations at different distances from the Galactic center. Since the DM distribution peaks towards the Galactic center, NSs in this region are expected to contain higher DM fractions that could lead to a different cooling behavior. Introduction Extremely high gravitational field and compactness inside neutron stars (NSs) make them a perfect laboratory to study the strongly interacting matter, test General Relativity and physics beyond the Standard Model [1, 2]. Throughout the entire stellar evolution, NSs could accumulate a sizeable amount of dark matter (DM) in their interior, which will impact the matter distribution, masses, radii, etc. [3–7]. At the end of its evolution, a main sequence star of 8-20 M⊙ undergoes a supernova explosion, creating an NS [8]. The former is from the gravitational collapse of molecular cloud regions, which exceed the Jeans limit. The proto-cloud may already present traces of DM, facilitating the collapse and giving rise to newly born stars with a sizeable amount of DM [9]. Once the star is born, DM particles could be further accreted from a surrounding medium, leading to an even higher DM fraction inside the object [10, 11]. At the end of the stellar evolution, the star eventually reaches the iron-core stage, undergoing a core-collapse supernova explosion. During this incredibly energetic event, DM might be created and further accrued inside the remnant, i.e. an NS [12]. More exotic scenarios can also be taken into account, e.g. mergers of baryonic matter (BM) stars with boson stars, and accretion of DM clumps [13]. Once the DM is trapped in the gravitational field of an NS, it may lead to different configurations depending on the DM properties: a core or halo configuration. In the former scenario, DM forms a compact core in the inner regions of an NS. A stronger gravitational pull by the inner Conclusion In this study, we focus on the effects of asymmetric fermionic DM on the NS thermal evolution. Despite asymmetric DM that interacts with BM only gravitationally contributes neither to neutrino, and photon emission directly nor deposits energy to the system, it alters the thermal evolution of NSs indirectly. We demonstrate that an accumulated DM pulls inwards BM from the outer layers, significantly increasing the central density, hence modifying the BM distribution. Consequently, the onset of the DU process is triggered at lower NS masses, leading to a highly efficient and rapid cooling, which is substantially different from the case when it is forbidden. At the same time, the proton fraction corresponding to the DU onset remains the same, as for the pure BM star with the same central BM density. We show that despite the DU process is kinematically allowed only at 1.91 M⊙ for the IST EoS and 1.92 M⊙ for the FSU2R EoS, an accumulation of DM particles with mχ = 1 GeV of fχ ≃ 0.161% (IST EoS) and fχ = 0.378% (FSU2R EoS) triggers the previously forbidden process. An increase of the DM particle’s mass mχ ≥ 3 GeV and/or DM fraction fχ ≥ 2 % shifts the DU onset even below 1.6 M⊙. This effect is also illustrated on the compact object in the center of the Cas A. Indeed, the surface temperature drop of Cas A could be explained by the rapid DU cooling triggered at a lower mass in comparison to the pure BM star. An additional effect of DM is related to the pull of BM inward, creating a more compact core and reduction of the baryonic radius. Thus, the total surface of the star is reduced leading to a lower photon luminosity. This effect is clearly visible at the photon-dominated stage when the neutrino emission takes a subdominant role.

Buy Unlock us Newsletters Abstract The Sun’s history is still a subject of interest to modern astrophysics. Observationally constrained CME rates of young solar analogues are still lacking, as those require dedicated monitoring. We present medium resolution optical spectroscopic monitoring of a small sample of bright and prominent solar analogues over a period of three years using the 0.5m telescope at observatory Lustbühel Graz (OLG) of the University of Graz, Austria. The aim is the detection of flares and CMEs from those spectra. In more than 1700 hours of spectroscopic monitoring we found signatures of four flares and one filament eruption on EK Dra which has been reported in previous literature, but we complementarily extended the data to cover the latter phase. The other stars did not reveal detectable signatures of activity. For these non-detections we derive upper limits of occurrence rates of very massive CMEs, which are detectable with our observational setup, ranging from 0.1 to 2.2 day−1 , but these may be even smaller than the given rates considering observational biases. Furthermore, we investigate the detectability of flares/CMEs in OLG spectra by utilizing solar 2D Hα spectra from MEES solar observatory. We find that solar-sized events are not detectable within our observations. By scaling up the size of the solar event, we show that with a fractional active region area of 18% in residual spectra and 72% in equivalent width time series derived from the same residuals that solar events are detectable if they had hypothetically occurred on HN Peg. Introduction The Sun has a 4.6 Gyr long history which was subject to numerous investigations. The “Sun in time” program (see e.g. Dorren & Guinan 1994; Güdel 2007) was founded to investigate the Sun’s history in great detail. The radiation environment was reconstructed from X-rays (e.g. Dorren et al. 1995; Güdel et al. 1997b; Telleschi et al. 2005; Guinan 2017), EUV (e.g. Güdel et al. 1997a; Tu et al. 2015), FUV (e.g. Guinan et al. 2003), UV (e.g. Dorren & Guinan 1994; Dalton et al. 2019), optical (e.g. Messina & Guinan 2002) to radio (e.g. Güdel et al. 1994; Villadsen et al. 2014; Fichtinger et al. 2017). The spectral energy distributions of the Sun in time has been inferred (Ribas et al. 2005; Claire et al. 2012) and also the solar wind in time has been investigated (Ó Fionnagáin & Vidotto 2018). Every study focusing on solar analogues of different age may be attributed to the idea of the “Sun in time” program. Transient activity phenomena like flares and CMEs of the young Sun can be characterized with a significant observational effort only as those are detectable via time series observations which require much observing time. Here, especially the CME environment of the young Sun remains still relatively unknown. However, flare frequency distributions, as well as flare power laws depending on the stars X-ray luminosity of young solar analogue stars and others have been presented by Audard et al. (2000). Based on these power laws Odert et al. (2017) have deduced relations to estimate stellar CME occurrence rates. Prior to Odert et al. (2017), Aarnio et al. (2012) established a methodology to relate solar flare/CME relations with stellar flaring relations to infer stellar CMEs and their parameters. Drake et al. (2013) applied a similar approach and identified the problem of the unknown stellar flare-CME association rate, as extrapolating to higher energies while using solar relations leads to unrealistic high energy requirements which have been not observed yet. Osten & Wolk (2015) assumed energy partition between bolometric flare radiation and kinetic energy of the associated CME. These authors found mass loss rates comparable to previous studies. To explain energy budget problem discussed in Drake et al. (2013), Odert et al. (2017) suggested then that probably the whole flare-CME association rate may shift to larger energies.Stellar flares are a subject of ongoing research going back to the first half of the last century where stellar flares have been detected using ground-based observations (Joy & Humason 1949; Luyten 1949, followed by numerous studies). With satellite missions such as the Microvariability and Oscillations of Stars Telescope (MOST), Convection, Rotation and planetary Transits (CoRoT), Kepler and now with the Transiting Exoplanet Survey Satellite (TESS) and in the near future also with the PLAnetary Transits and Oscillation of stars mission (PLATO) long-term photometric measurements were and will be accessible. This enabled statistical investigations of flares (see e.g. Balona 2015; Davenport 2016) and superflares ((E>1033 erg), see e.g. Maehara et al. 2012; Tu et al. 2020; Doyle et al. 2020; Tu et al. 2021; Okamoto et al. 2021). Flare-frequency distributions from TESS or Kepler are determined for more energetic flares, as usually such broadband photometric observations are insensitive to low energetic flares, as those simply leave no signature in a light-curve and are hidden in the noise.and are hidden in the noise. Stellar CMEs have been detected so far mainly on dMe stars (e.g. Houdebine et al. 1990; Guenther & Emerson 1997; Vida et al. 2016) using the method of Doppler shifted emission. This method uses the signature of plasma being ejected from a star. The signature, either appearing in absorption or emission is Doppler shifted by its projected velocity. This signature is often very pronounced in Balmer lines similarly to erupting filaments/prominences on the Sun. Optical spectroscopic monitoring programs to search for stellar CMEs using the method of Doppler shifted emission/absorption are often focused on dMe stars, as those are known to frequently flare and therefore also possibly may host CMEs. dG stars reveal also frequent flares if their X-ray luminosity is large, i.e. their activity level is high. However, for the detection of flares and CMEs, only stronger events, compared to dMe stars, may be detected, because of the higher continuum around Hα on those stars, or in other words a higher contrast is favorable for stellar CME detection using the method of Doppler-shifted emission/absorption in the Hα line.Only recently Namekata et al. (2021) presented the detection of a blue wing absorption in Hα during a superflare on the young solar analogue EK Dra, which the authors interpreted as an erupting filament. This event was simultaneously observed by two telescopes. Inoue et al. (2023) report on the detection of a high velocity blue-wing emission feature being interpreted by the authors as prominence eruption on the RS CVn system 1355 Ori, consisting of a K2-4 sub-giant and a G1 dwarf. Even more recently Namekata et al. (2024) focus again on EK Dra and present this time two prominence eruptions from which one has a projected bulk velocity being above the escape velocity of EK Dra and reveals a simultaneously observed candidate of coronal dimming. Using the method of Doppler shifted emission/absorption numerous candidate events have been found especially on dMe stars (e.g. Fuhrmeister et al. 2018; Vida et al. 2019). With this method only events with a projected bulk velocity being greater the stars’ escape velocity can be treated as eruptive events. It can be concluded that they are escaping from the star, as their true velocities can be even higher. But in numerous studies events with much smaller projected bulk velocities have been found which are much more difficult to interpret, as those may also originate from flaring plasma motions. To better interpret these spectral signatures investigating the Sun seen as a star may help. Instruments doing solar 2D spectroscopy are rare. In the 90ies of the last century MEES CCD provided Hα 2D spectroscopy of a cut-out of the solar-disk, in 2016 SMART/SDDI went into operation, doing full-disk multi-filter measurements resulting in a full-disk Hα profile, and only recently the Chinese Hα Solar Explorer (CHASE) providing full-disk Hα spectroscopy. MEES did Hα 2D Hα spectroscopy of solar cycles 22 and 23, so representing the past, whereas SMART/SDDI operated during the second half of cycle 24 and cycle 25 and CHASE beginning of cycle 25 up to now and hopefully also in the future. Spectroscopic Sun-as-a-star observations date back to the seventies of the last century (e.g. Livingston et al. 1981). Spatial integrated investigations of flares and erupting filaments have been presented by e.g. Den & Kornienko (1993); Ding et al. (2003); Ichimoto et al. (2017) and only recently progress has been made especially to understand Balmer line asymmetries related to erupting filaments/prominences (Namekata et al. 2021; Leitzinger et al. 2021; Namekata et al. 2022b; Otsu et al. 2022; Otsu & Asai 2024; Ma et al. 2024), as the Sun is the only star where we can actually see if a CME occurred in spatial and temporal vicinity to a filament/prominence eruption.

The observations revealed a very low level of detectable activity in Hα for the majority of stars in the sample except for EK Dra, the youngest star in the sample. In the period from January to April 2020 we have detected spectroscopically four flares and one episode of a filament eruption on EK Dra. The eruptive event has been also published by Namekata et al. (2021) who observed EK Dra at the same time. We have started observing when the eruptive event was already ongoing and captured the late stages of the eruption and the back falling material until the signature vanished. With our observations from OLG we could complement the erupting filament revealing its full evolution. In the typical exposure times used for spectroscopic monitoring at OLG (three minutes) we did not see the absorption signature caused by an eruptive filament on EK Dra. Building half hour averages revealed the absorption signatures. To estimate the detectability of solar activity events on our target stars, we spatially integrate over an active solar region revealing a complex event including flares, filament eruptions and back falling material observed by MCCD on MSO, similar to the event on EK Dra. As expected, when superimposing the spectral spatially integrated solar residuals of a solar event on a typical OLG spectrum of e.g. HN Peg then it remains invisible. One needs to increase the event area to make the signature visible in a spectrum. We need to scale the active region with factors resulting in a fractional area of the active region being 18% in residual spectra and 72% in equivalent width time series, respectively, to make the signature detectable above the noise. This behaviour is consistent with the fact that younger stars have larger active areas and therefore those can be detected in stellar spectra, whereas solar active regions are too small relative to the solar disk to be seen in full disk integrated light i.e. Sun-as-a-star observations. However, even on the other stars of the sample, activity signatures had been expected (from the Hα flare rates) but were not visible in the data. We therefore conclude that on solar-like stars already in the first few hundred of Myr the occurrence rates of more massive eruptive filaments/prominences decreases significantly. With our observational setup we might have detected massive events only. The intention of this study was the statistical determination of parameters of stellar eruptive filaments/prominences and their relation to flares. We found four flares and one filament eruption on one star. We know that the filament eruption was accompanied by a flare but the other four flares did not show signatures of filament eruptions. So one out of five flares on EK Dra shows an accompanying filament eruption, but this result is far from being statistically significant. Although the observational efforts have been increased in the past few years to detect stellar CMEs still the number of distinct events is low. We know many more candidate events, at least for the method of Doppler-shifted absorption/emission (e.g. Fuhrmeister et al. 2018; Vida et al. 2019). One way to obtain statistics is to focus on the numerous (few hundreds) candidate events and try to better understand those. This has already partly begun with the systematic investigation of spatially integrated solar, i.e. Sun-as-a-star signatures of flares and eruptive filaments, with the aim to better characterize stellar signatures of flares and eruptive filaments/prominences, including their temporal evolution (see e.g. Leitzinger et al. 2021; Namekata et al. 2021; Leitzinger 2022; Otsu et al. 2022). These studies used solar instruments capable of spatially resolved 2D spectroscopy (such as MCCD on Mees Solar Observatory/MSO) or full-disk photometry in various filters (Solar Dynamics Doppler Imager/SDDI on The Solar Magnetic Activity Research Telescope/SMART). With this study we have demonstrated that small-sized telescopes can be used to infer spectroscopic activity signatures on bright solar-like stars. From the spectroscopic monitoring presented in this study we have seen that CMEs, more energetic and massive than occurring on our present-day Sun, on few hundred Myr old solar analogues are not a frequent phenomenon.
