Asteroseismology of Gamma Doradus stars with Kepler

Abstract:

We propose to observe, on the one hand, a sample of candidate new Gamma Doradus stars in the Kepler FoV for long-term monitoring to detect their high-order gravity modes. This will allow a careful study of the interaction of convection and g-mode oscillations. Moreover, we seek to establish, for the first time, the simultaneous occurrence of gravity-mode and stochastically-excited pressure-mode oscillations in a smal subsample of carefully chosen targets. Gamma Doradus stars have the potential to exhibit both these types of oscillations, which probe very different inner stellar regions. Thus they hold great potential for high-precision asteroseismic inferences of their interior structure.
