Título/Title: The formation of the Milky Way: the key role of spectroscopic surveys and asteroseismology
Resumo/Abstract:
Many ongoing (SDSS-SEGUE, SDSS-APOGEE, RAVE) and future (HERMES, 4MOST)
surveys have the main goal to
map the complex kinematical and chemical substructure of the Galaxy. The
final aim is to constrain the assembly and
chemical enrichment histories of the Milky Way. In addition, by
exploiting the combination of asteroseismic data from Kepler and Corot
satellites for giant stars with the abundance and kinematical
information provided by ground-based surveys, it should be
possible to obtain precise ages for large samples of stars.
