Like terrestrial seismology, asteroseismology is the study of star quakes. These internal vibrations are detected by observing the luminosity (or velocity) variations at the stellar surfaces. From these time series, one computes power spectra which contain a wealth of information. In particular, for solar-like pulsators, we are able to observe the signal of granulation as well as the eigenmodes of stellar oscillations, both of which are a direct consequence of the convection in the star's envelope. Asteroseismology allows us to probe the interior of stars much like an ultrasound. Furthermore, with the large spatial photometric surveys CoRoT and Kepler, a new scope for seismology appeared. Indeed, it is possible to characterise to first orde...
