EPJ Web of Conferences, 2023 Polytropes, Virial theorem, evolutionary time scales, degrees of freedom, radiative transport, molecular weight, degeneracy, Jeans mass, and Eddington luminosity are basic ingredients to describe the physics of stars.

Stellar evolution and the Standard Solar Model [PDF]
EPJ Web of Conferences, 2020 This contribution is meant as a very brief introduction to the principal concepts of stellar physics. First the main physical processes active in stellar structures will be shortly described, then the most important features during the stellar life-cycle

Toward a New Paradigm in the Analysis of Asteroseismic Lightcurves
Frontiers in Astronomy and Space Sciences, 2020 This paper aims at being a provocative guide to the future of asteroseismology from the perspective of the analysis of time series, where the fundamentals of harmonic analysis are subjected to stress tests.

The stellar atmosphere physical system I. Phenomenological definition and representation of a stellar atmosphere [PDF]
Serbian Astronomical Journal, 2018 This paper is the first in a series of two that deals with the physical and numerical grounds of stellar atmosphere modelling. After a phenomenological definition of a star and stellar atmosphere, the physics that shapes the stellar atmosphere ...

The Astronomical Journal, 2023 In this paper, we report on the follow-up of six potential exoplanets detected with Gaia astrometry and provide an overview of what is currently known about the nature of the entire Gaia astrometric exoplanet candidate sample, 72 systems in total.

Approximate input physics for stellar modelling [PDF]
, 1995 We present a simple and efficient, yet reasonably accurate, equation of state, which at the moderately low temperatures and high densities found in the interiors of stars less massive than the Sun is substantially more accurate than its predecessor by ...

Hot super-Earths stripped by their host stars
Nature Communications, 2016 Theory predicts a deficit of super-Earth sized planets, which orbit close to their host star. Here, Lundkvist et al. use data from the NASA Kepler mission to show that this deficit is also seen in observations, thereby providing new insight into ...

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-
