Tell me how you oscillate, I will tell you who you are

The space missions CoRoT and Kepler provide us with unique asteroseismic results that drastically change our views on the stellar interior structure. Inferring relevant estimates of the stellar masses and radii for field stars is now common, as well as determining their evolutionary status or the core rotation rate. A focus on red giant seismology helps understanding how new observable carry information on the stellar interior structure, including a direct view into the stellar core . Ensemble asteroseismology based on global seismic properties is used to link the seismic observables with convection properties. Individual modelling is crucial for addressing the stellar physics in detail, with major consequences for exoplanet-hosting stars.
