The BaSeL library as a basic tool to provide fundamental stellar parameters of future space missions: COROT and GAIA

COROT and GAIA are two future major space missions directly connected to most of the stellar astrophysic questions, from stellar physics to evolution of galaxies. We describe a project for the preparation of these two missions by using the possibilities of the ``BaSeL'' models, a library of theoretical stellar energy distributions, to provide automatically the fundamental stellar parameters of the candidate stars. We present the results already obtained for the stars of the COROT main programme.
