A need to revise stellar opacities from asteroseismology of Scuti stars
Jadwiga Daszyńska-Daszkiewicz, Przemysław Walczak, Alexey Pamyatnykh +2
We construct seismic models of the four double-mode radial Scuti stars adopting opacities from three databases: OPAL, OP and OPLIB. The aim is to find the models that fit the o…
On accretion in the eclipsing polar BS Tri
A. I. Kolbin, N. V. Borisov, N. A. Serebriakova +4
We analyze spectroscopic and photometric observations of the eclipsing polar BS Tri. The polar's light curve shape variations can be interpreted by changing contributions of the ac…
The HI Content of Red Geyser Galaxies
Emily Frank, David V. Stark, Karen Masters +5
Red geysers are a specific type of quiescent galaxy, denoted by twin jets emerging from their galactic centers. These bisymmetric jets possibly inject energy and heat into the surr…
Sulfur Ion Implantations Into Condensed CO2: Implications for Europa
D. V. Mifsud, Z. Kaňuchová, P. Herczku +12
The ubiquity of sulfur ions within the Jovian magnetosphere has led to suggestions that the implantation of these ions into the surface of Europa may lead to the formation of SO2.…
Gaia22eor: Symbiotic star V2756 Sgr detected in a deep eclipse
Jaroslav Merc, Hamish Barker, Rudolf Gális
V2756 Sgr is a long-known S-type symbiotic binary that was recently detected in 1 mag eclipse-like fading by the Gaia satellite. This behavior was reported as a Gaia Science…
Chaos in multiplanetary extrasolar systems
Pavol Gajdoš, Martin Vaňko
Here we present an initial look at the dynamics and stability of 178 multiplanetary systems which are already confirmed and listed in the NASA Exoplanet Archive. To distinguish bet…
GRaM-X: A new GPU-accelerated dynamical spacetime GRMHD code for Exascale computing with the Einstein Toolkit
Swapnil Shankar, Philipp Mösta, Steven R. Brandt +3
We present GRaM-X (General Relativistic accelerated Magnetohydrodynamics on AMReX), a new GPU-accelerated dynamical-spacetime general relativistic magnetohydrodynamics (GRMHD) code…
Iterative construction of the optimal sunspot number series
Michal Švanda, Martina Pavelková, Jiří Dvořák +1
The relative number of sunspots represents the longest evidence describing the level of solar activity. As such, its use goes beyond solar physics, e.g. towards climate research. T…
Effective resistivity in relativistic collisionless plasmoid-mediated reconnection
Sebastiaan Selvi, Oliver Porth, Bart Ripperda +3
Magnetic reconnection can power spectacular high-energy astrophysical phenomena by producing non-thermal energy distributions in highly magnetized regions around compact objects. B…
Near-Infrared and Optical Observations of Type Ic SN 2021krf: Luminous Late-time Emission and Dust Formation
Aravind P. Ravi, Jeonghee Rho, Sangwook Park +29
We present near-infrared (NIR) and optical observations of the Type Ic supernova (SN Ic) SN 2021krf obtained between days 13 and 259 at several ground-based telescopes. The NIR spe…
Searching for compact objects in the single-lined spectroscopic binaries of the young Galactic cluster NGC 6231
G. Banyard, L. Mahy, H. Sana +7
Recent evolutionary computations predict that a few percent of massive OB stars in binary systems should have a dormant BH companion. Despite several reported X-ray quiet OB+BH sys…
Luminosity distribution of fast radio bursts from CHIME/FRB Catalog 1 by means of the updated Macquart relation
Xiang-Han Cui, Cheng-Min Zhang, Di Li +9
Fast radio bursts (FRBs) are extremely strong radio flares lasting several micro- to milliseconds and come from unidentified objects at cosmological distances, most of which are on…
Variability of eclipse timing:the case of V471 Tauri
Emil Kundra, Ľubomír Hambálek, Siegfried Vanaverbeke +4
The post-common envelope binary V471 Tauri has been an object of interest for decades. V471 Tau shows various phenomena due to its evolutionary state and unique properties, e.g. it…
Enabling the discovery of fast transients: A kilonova science module for the Fink broker
B. Biswas, E. E. O. Ishida, J. Peloton +4
We describe the fast transient classification algorithm in the center of the kilonova (KN) science module currently implemented in the Fink broker and report classification results…
KiDS-1000: Combined halo-model cosmology constraints from galaxy abundance, galaxy clustering and galaxy-galaxy lensing
Andrej Dvornik, Catherine Heymans, Marika Asgari +14
We present constraints on the flat CDM cosmological model through a joint analysis of galaxy abundance, galaxy clustering and galaxy-galaxy lensing observables with the Kilo-Deg…
Energetic Electron Irradiations of Amorphous and Crystalline Sulphur-Bearing Astrochemical Ices
Duncan V. Mifsud, Péter Herczku, Richárd Rácz +10
Laboratory experiments have confirmed that the radiolytic decay rate of astrochemical ice analogues is dependent upon the solid phase of the target ice, with some crystalline molec…
Data on 824 fireballs observed by the digital cameras of the European Fireball Network in 2017-2018. I. Description of the network, data reduction procedures, and the catalog
J. Borovicka, P. Spurny, L. Shrbeny +10
A catalog of 824 fireballs (bright meteors), observed by a dedicated network of all-sky digital photographic cameras in central Europe in the years 2017-2018 is presented. The stat…
Revisiting the Transit Timing Variations in the TrES-3 and Qatar-1 systems with TESS data
