Abstract

GAIA will be of paramount importance to understand the Galacticstructure. Here we focus on the determination of the star formationhistory (SFH) of the Galactic disk and bulge. We discuss whether GAIAwill be able to isolate a sample of stars with the samecharacteristics of Hipparcos data (completeness over a certaincritical magnitude and high precision in the distance) which will castlight on the SFH of the whole disk. We analyze the expected results intwo directions, namely the BW and the Galactic pole. Finally wediscuss the contribution of GAIA to the study of the SFH of the bulge.
