Thanks to CoRoT (CNES) and Kepler (NASA) seismic observations, it is now possible to detect many solar-like oscillations in a very high number of stars. The observed oscillation spectra can be quite complicate to analyse and interpret. Nevertheless, these spectra show characteristic pattern, which can be more simply characterized with that we call stellar seismic indices. More specifically, the stellar seismic indices correspond to characteristic global seismic numbers that are extracted from the oscillation spectra of solar-like pulsating stars.
