Invited_talk abstract details

The discovery of the 5-min oscillations in the Sun almost 50 years ago has opened a wonderful window on its interior that has deeply renewed the view we had on our star. Helioseismology has provided very accurate constraints on solar structure and dynamics, with consequences for the whole stellar evolution. These highly exciting results have naturally stimulated the research of such acoustic pulsations in other solar-like stars. The low amplitudes of these stochastically-excited oscillations make their detections very challenging. The first doubtless detection and identification of p modes in $\alpha$ Cen A in 2001, that have been possible thanks to the development of high-performance spectrographs, marked the birth of a new investigation field. The launch of CoRoT 2 years ago has produced a quantitative leap for solar-like-star seismology by delivering 5-month-long uninterrupted time-series of high-precision photometric data. Now, several F and G main-sequence stars have been analyzed. During this review, we discussed the current status of these observations, what we are learned from them about solar-like star properties (mass, radius, rotation, inclination, convection properties...) before concluding on perspectives offered by the very long Kepler observations.
