Hot subdwarf wind models with accurate abundances. I. Hydrogen dominated stars HD 49798 and BD+18° 2647
Original language description
We aim to understand the influence of metallicity on the strength of the winds of the hot hydrogen-rich subdwarfs HD 49798and BD+18◦2647. We used high-resolution UV and optical spectra to derive stellar parameters and abundances using the TLUSTY andSYNSPEC codes. For derived stellar parameters, we predicted wind structure (including mass-loss rates and terminal velocities) withour METUJE code. Wind models with accurate abundances provide more reliable wind parameters, but the influence of abundances on thewind parameters is limited in many cases
