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…
