MPS Seminar: Galactic Archaeology with asteroseismology and spectroscopy (F. Anders)
I will present first results obtained from a combined dataset of 700 red giant stars in two fields of the Galactic disc which have been co-observed by the CoRoT satellite and the APOGEE spectrograph. We have measured chemical abundance patterns and ages of field stars over a large radial range of the Milky Way's disc, and present recent results on the dependence of abundance distributions on age and position in the disc. A particularly intriguing result is that the tight correlation between age and chemical abundances previously seen in the Solar vicinity does not seem to be valid for the inner Galactic disc: [alpha/Fe]-rich stars are not necessarily old.
