The Oldest Stellar Populations and the Age of the Universe
Osservatorio Astronomico, Via Ranzani 1, 40127
Bologna, Italy
The study of the oldest stellar populations in the Galaxy provides important cosmological information (e.g. a lower limit to the age of the Universe) and helps constraining models of galaxy formation. The most commonly used stellar age indicators are reviewed and discussed, and the impact of GAIA on these topics is estimated.
