Asteroseismology and evolution of GW Vir stars.


Abstract (from CDS):

We present a summary of current knowledge of the hot, pulsating, hydrogen deficient GW∼Vir stars. At \Teff≃120,000∼K and with an atmosphere composed mainly of helium, carbon, and oxygen, these pulsating stars are showing multiperiodic, intermediate- to high-order g∼modes. They include in their class some of the hottest white dwarfs and planetary nebulae. We present non-adiabatic asteroseismology results used to determine the atmospheric parameters of GW∼Vir stars. We also discuss some of the latest asteroseismology results using state of the art post-Asymptotic Giant Branch evolution models.
