Final Report Summary - STELLARAGES (Accurate ages of stars)
The outcome of the Stellar Ages project shows that asteroseismology – the study of the internal structures of stars through their global oscillations – indeed provides important constraints to determine stellar ages. Furthermore, the measurements of the surface chemical composition of the star provide vital information. With this information we have been able to determine stellar ages with a median relative uncertainty of 10% for Sun-like stars. For more evolved stars we have also been able to make significant progress towards this level of accuracy.
