Doppler asteroseismology from Dome C: goals and prospects
Laboratoire d'Astrophysique de Marseille, Traverse du
Siphon, BP. 8, 13376 Marseille, France
Recent results of asteroseismology have been achieved on a growing list of solar-type stars thanks to high precision echelle spectrographs. These results indicates that Doppler measurements are more efficient from the ground than photometry for p-modes detections. A high precision spectrograph dedicated for Doppler asteroseismology based in Dome C will play an important and fundamental step in asteroseismology. Such an instrument coupled to an only 1-m class telescope will be able to reach a very high level of sensibility for p-mode detection on several tens of solar-type stars. Capabilities and expected performances in asteroseismology of a replica of the SOPHIE spectrograph (1.93-m OHP) based in Dome C are presented. Such an instrument is furthermore fully compatible and adapted for polarimetry studies and detection and characterization of extra-solar planets.
