Evolutionary variations of superficial iron and calcium abundance in main sequence A stars

Yu. A. Fadeyev, R. M. Bayazitov

Main sequence stellar evolution models were computed together with solution of the equations of atomic diffusion for 16 elements from hydrogen to nickel. The grid of evolutionary t…

Models of long-period variables of the globular cluster 47 Tuc

Yu. A. Fadeyev

Stellar evolution computations were carried out for stars with a main sequence mass and initial metal abundance and . Selected mode…

Elusive helium stars in the gap between subdwarfs and Wolf-Rayet stars~II. Nonlinear pulsations of stripped helium stars

Yu. A. Fadeyev, A. G. Kuranov, L. R. Yungelson

It is shown for the first time that the stripped helium stars with masses 2 to 7 solar mass which are formed in close binary systems in the so-called case B of mass-exchange and re…

Models of Mira variables of the Large Magellanic Cloud

Yu. A. Fadeyev

Consistent stellar evolution and nonlinear radial stellar pulsation calculations were carried out for models of asymptotic giant branch stars with initial masses $1.5M_\odot\le M_\…

Revision of calcium and scandium abundances in Am stars based on NLTE calculations and comparison with diffusion stellar evolution models

L. I. Mashonkina, Yu. A. Fadeyev

The homogeneous data sets for the calcium and scandium abundances accounting for departures from LTE were obtained for a sample of 54 metallic-line (Am) stars. The Ca and Sc abunda…
