Y Asteroseismology of Kepler ZZ Ceti Stars with Fully Evolutionary Models
Original language description
Recently the Kepler spacecraft observed ZZ Ceti stars giving the opportunity to study their variability for long baselines. We present a study of pulsational properties of two ZZ Ceti stars observed with the Kepler spacecraft: GD 1212 and SDSS J113655.17+040952.6, based on a grid of full evolutionary models of DA white dwarf stars, characterized by detailed and consistent inner chemical profiles. For J113655.17+040952 we found values of gravity and effective temperature in good agreement with spectroscopy. For GD 1212 the asteroseismological fits show a stellar mass higher than the spectroscopic value, but in agreement with the determinations from photometry coupled with parallax.
