Galactic archeology with TESS: prospects for testing the star formation history in the solar neighborhood

Uncertainties in the age distribution of stars in the solar neighbourhood have thus far limited the determination of the star formation history of the local galactic disk, which is one of key constraints to test competing models of formation and evolution of the Milky Way. It is hoped that this barrier may be overcome with the reception of all-sky asteroseismic data. In this contribution we investigate whether the TESS mission will be able to make a substantial contribution to the field of galactic archaeology. We use the TRILEGAL code to generate a set of synthetic stellar populations, and considered only stars which would display oscillations detectable by TESS. We then investigate the extent to which the mission would be able to distinguish between models generated assuming different star-formation-history models.
