TalkStellar seismology of gamma Dor pulsators in times of the CoRoT and Kepler satellite missions.
Gamma Dor stars (M = 1.2-2.5 M⊙; spectral type A-F) are very interesting from an asteroseismic point of view. They show gravity modes, which are the only modes...

PublicationThe tip of the iceberg: the frequency content of the δ Sct star HD 50844 from CoRoT space photometry
It has been suggested that the detection of a wealth of very low amplitude modes in δ Sct stars was only a matter of signal-to-noise ratio. Access to this...
