SUMMARY:Stellar seismology of gamma Dor pulsators in times of the CoRoT and
  Kepler satellite missions.
DESCRIPTION:Stellar seismology of gamma Dor pulsators in times of the CoRoT
  and Kepler satellite missions.\nDr. Katrien Uytterhoeven\n\nGamma Dor sta
 rs (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 m
 odes that provide information on the deep stellar interior. Observationall
 y they are very challenging targets. Typical pulsation periods are of the 
 order of a day and amplitudes are fairly small (below 0.05 mag; 2 km/s), m
 aking it extremely difficult to monitor the periodic variations from the g
 round. The asteroseismic space missions CoRoT and Kepler are providing uni
 nterrupted time-series from space, with unprecedented accuracy, and hence 
 promise a revolution in the study of gamma Dor stars. I will present resul
 ts of the seismic analysis of CoRoT and Kepler gamma Dor targets, and the 
 associated ground-based support observations, involving many telescopes at
  different observatories (including La Palma and Izaña).
