| Abstract: |
We present a novel approach for asteroseismology of DA and DB white
dwarfs that consists in the employment of large sets of non-static,
physically sound, fully evolutionary models representative of these
stars. Our approach combines (i) a significant exploration of the
parameter space (M*, Teff, MH, etc), and
(ii) a detailed and updated input physics, in particular regarding the
internal chemical structure, that is a crucial aspect for correctly
interpret the information embedded in the pulsation spectra of these
stars. We already have applied this approach with success on
pulsating PG1159 stars (DOV or GW Vir variables). Here, we apply our
approach to an ensemble of 44 bright DAV stars, and also to the
recently discovered DAV star WD J1916+3938 (Hermes et al. 2011) and DBV star KIC 8626021 (Ostensen et al. 2011), both
stars located in the field of view of the Kepler Mission. |
