Abstract:
We discuss the tracing of star formation histories with ESAs spaceastrometry mission GAIA, emphasizing the advantages of AGB stars for thepurpose. GAIAs microarcsecond-level astrometry, multi-band photometryand spectroscopy will provide individual distances, motions,T<SUB>eff</SUB>, log g and [M/H for vast numbers of AGB stars in theGalaxy and beyond. Reliable ages of AGB stars can be determined todistances of 200 kpc in a wide range of ages and metallicities,allowing star formation histories to be studied in a diversity ofastrophysical environments.
