Hybrid gamma Doradus - delta Scuti pulsators: New Insights into the physics of the oscillations from Kepler observations
Grigahcene A.
Abstract
We present stellar modeling results for three G-type stars observed by Kepler. The observations, made at one-minute cadence during the first 33.5d of science operations, reveal high signal-to-noise solar-like oscillation spectra in all three stars: about 20 modes of oscillation can be clearly distinguished in each star. We discuss inferences on the stellar properties obtained by comparing the characteristic spacings, individual frequencies and spectroscopic constraints with grids of stellar evolution models.
