Abundance analyses of cool extreme helium stars
Extreme helium stars (EHes) with effective temperatures from 8000 to 13 000 K are among the coolest EHes and overlap the hotter R CrB stars in effective temperature. The cool EHes may represent an evolutionary link between the hot EHes and the R CrB stars. Abundance analyses of four cool EHes, BD118 4381 (FQ Aqr), LS IV 2148 109, BD 218 3438 (NO Ser) and LS IV 218 002 (V2244 Oph), are presented...
متن کاملSubluminous B Stars and Progenitors of Helium Core White Dwarfs
It is now generally accepted that the subluminous B (sdB) stars can be identified with models for Extreme Horizontal Branch (EHB) stars burning He in their core, but with a very tiny inert hydrogen envelope (Heber, 1986). An EHB star bears great resemblance to a helium main-sequence star of half a solar mass and its further evolution should proceed similarly (i.e. directly to the white dwarf gr...
متن کاملAbundance analyses of roAp stars
In this sixth paper in a sequence on abundance analyses of roAp stars we present the results for two further members of this group, which are fairly similar and have only a small magnetic field. The analysis of 10 Aql and HD 122970 did not require, for the first time in this long term project, the development of tools and hence was rather straight-forward. We reanalyzed Sm, Eu and Gd in HD 2039...
متن کاملModeling binary stars: age, helium abundance, and convection parameters
Stellar evolutionary models simulate well binary stars when individual stellar mass and system metallicity are known. The main goal of this paper is to determine a set of stellar parameters (mass, age, helium abundance, and convection parameters) for binary systems formed by FGK main-sequence stars of Population I. For a selected group of seven binaries, where luminosity, e ective temperature, ...
متن کاملThe Origin of Helium-Rich Subdwarf O Stars
The origin of helium-rich subdwarf O stars (He-sdO) is still unclear. Significant progress has been made recently in placing them in the Hertzsprung–Russell diagram. However, the question of their progenitors is still unsolved. It is unclear which types of stars evolve into He-sdOs and whether they are formed by all galactic populations. Here I will present results of a radial velocity (RV) sur...
