Kepler Asteroseismology Program: Introduction and First Results
Gilliland, RL; Timothy M Brown; Jorgen Christensen Dalsgaard; Hans Kjeldsen; Conny Aerts; Thierry Appourchaux; Sarbani Basu; Timothy R BeddingAsteroseismology involves probing the interiors of stars and quantifying their global properties, such as radius and age, through observations of normal modes of oscillation. The technical requirements for conducting asteroseismology include ultrahigh precision measured in photometry in parts per million, as well as nearly continuous time series over weeks to years, and cadences rapid enough to sample oscillati...
CoRoT measures solar-like oscillations and granulation in stars hotter than the...

The extension of similar studies to more distant stars has raised many difficulties despite the strong efforts of the international community over the past decades. The CoRoT (Convection Rotation and Planetary Transits) satellite, launched in December 2006, has now measured oscillations and the stellar granulation signature in three ma...
