Deep asteroseismic sounding of the compact hot B subdwarf pulsator KIC02697388 from Kepler time series photometry

The frequency spectrum of the subdwarf B pulsator KIC02697388 is presented. A long, continuous time series of high-precision photometry taken with the Kepler satellite is utilised. KIC02697388 is a gravity-mode pulsator, which allows the "sounding" of the stellar core. In addition, one pressure-mode is identified, making the star one of the rare hybrid sdB pulsators.
