Floating dark matter in celestial bodies
Journal of Cosmology and Astroparticle Physics, 2023 Abstract Dark matter (DM) can be captured in celestial bodies after scattering and losing sufficient energy to become gravitationally bound. We derive a general framework that describes the current DM distribution inside celestial objects, which self-consistently includes the effects of concentration diffusion, thermal diffusion, gravity,

Close-In Substellar Companions and the Formation of sdB-Type Close Binary Stars
Acta Polytechnica CTU Proceedings, 2015 The sdB-type close binaries are believed to have experienced a common-envelope phase and may evolve into cataclysmic binaries (CVs). About 10% of all known sdB binaries are eclipsing binaries consisting of very hot subdwarf primaries and low-mass ...

Random forest Algorithm for the Classification of Spectral Data of Astronomical Objects
Algorithms, 2023 Over time, human beings have built increasingly large astronomical observatories to increase the number of discoveries related to celestial objects. However, the amount of collected elements far exceeds the human capacity to analyze findings without help.
