Databases of Publications and Observations as a Part of the Crimean Astronomical Virtual Observatory
Open Astronomy, 2015 We describe the main principles of formation of databases (DBs) with information about astronomical objects and their physical characteristics derived from observations obtained at the Crimean Astrophysical Observatory (CrAO) and published in the ...

Stellar Flare Statistics - Physical Consequences [PDF]
International Astronomical Union Colloquium, 1989 AbstractThe observational data permit us to establish clear statistical correlations between different parameters of stellar flare activity and the characteristics of quiet stars. These relations are: (i)between energies and frequencies of flares on stars of different luminosities;(ii)between total radiation energies of flares and quiet stars both in X-

Turbulence-supported Massive Star Envelopes
The Astrophysical Journal Letters, 2023 The outer envelopes of massive ( M ≳ 10 M _⊙ ) stars exhibit large increases in opacities from forests of lines and ionization transitions (particularly from iron and helium) that trigger near-surface convection zones. One-dimensional (1D) models predict

What asteroseismology can do for exoplanets
EPJ Web of Conferences, 2015 We describe three useful applications of asteroseismology in the context of exoplanet science: (1) the detailed characterisation of exoplanet host stars; (2) the measurement of stellar inclinations; and (3) the determination of orbital eccentricity from ...

Investigation of ρ Cas (HR 9045, HD 224014) stellar atmosphere [PDF]
Serbian Astronomical JournalThe atmosphere of hypergiant ρ Cas is investigated by the method of atmospheric model. Effective temperature and the surface of gravity are determined by comparing the observed and theoretical values of photometrical indices [c1];Q, and ...

Asteroseismology of High-Mass Stars: New Insights of Stellar Interiors With Space Telescopes
Frontiers in Astronomy and Space Sciences, 2020 Massive stars are important metal factories in the Universe. They have short and energetic lives, and many of them inevitably explode as a supernova and become a neutron star or black hole.

Inversions of Stellar Structure From Asteroseismic Data
Frontiers in Astronomy and Space Sciences, 2022 The advent of space-based photometry missions in the early 21st century enabled the application to asteroseismic data of advanced inference techniques until then restricted to the field of helioseismology.

Revealing the Galaxy–Halo Connection through Machine Learning
The Astrophysical Journal, 2023 Understanding the connections between galaxy stellar mass, star formation rate, and dark matter halo mass represents a key goal of the theory of galaxy formation. Cosmological simulations that include hydrodynamics, physical treatments of star formation,

Looking into dark matter with asteroseismology
Frontiers in Astronomy and Space Sciences, 2022 Dark matter remains as an elusive component of modern Cosmology. According to previous research, stellar physics observables can be affected by the presence of hypothetical dark matter particles, which can be produced or accreted into the stars.
