Databases of Publications and Observations as a Part of the Crimean Astronomical Virtual Observatory

open access: yesOpen 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 ...

Asteroseismology of High-Mass Stars: New Insights of Stellar Interiors With Space Telescopes

open access: yesFrontiers 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.

Revealing the Galaxy–Halo Connection through Machine Learning

open access: yesThe 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,

What asteroseismology can do for exoplanets

open access: yesEPJ 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 ...

MESA ISOCHRONES AND STELLAR TRACKS (MIST) 0: METHODS FOR THE CONSTRUCTION OF STELLAR ISOCHRONES [PDF]

open access: yes, 2016
I describe a method to transform a set of stellar evolution tracks onto a uniform basis and then interpolate within that basis to construct stellar isochrones.

Physics of Stellar Coronae [PDF]

open access: yes, 2009
Stellar coronae, defined by the ensemble of magnetic field structures above stellar photospheres and chromospheres together with their thermal or non-thermal plasma content, play an important role in our understanding of stellar magnetic fields, the stellar magnetic dynamo, and interactions between a star and its environment.

The γ Dor stars as revealed by Kepler: A key to reveal deep-layer rotation in A and F stars

open access: yesEPJ Web of Conferences, 2017
The γ Dor pulsating stars present high-order gravity modes, which make them important targets in the intermediate-and low-mass main-sequence region of the Hertzsprung-Russell diagram. Whilst we have only access to rotation in the envelope of the Sun, the

Progress on nuclear reaction rates affecting the stellar production of 26Al

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2022
The radioisotope 26Al is a key observable for nucleosynthesis in the Galaxy and the environment of the early Solar System. To properly interpret the large variety of astronomical and meteoritic data, it is crucial to understand both the nuclear ...
