Andrea Miglio Title: Bridging the fields of asteroseismology and galactic stellar population studies Abstract:The detection of radial and non-radial solar-like oscillations in thousands of G-K giants with CoRoT and Kepler is paving the road for detailed studies of stellar populations in the Galaxy. The available average seismic constraints allow largely model-independent determination of stellar surface gravities, radii, and masses. We argue that G-K giants showing solar-like oscillations represent a new class of accurate distance indicators: thanks to CoRoT and Kepler observations we can now map the position of thousands of stars in different regions of the Milky Way. Moreover, we will present a first comparison between the populations of giants in the first two CoRoT fields, suggesting evidence of a vertical mass (hence age) gradient in the disk, in qualitative agreement with synthetic stellar populations simulated with TRILEGAL. For a quantitative estimate of such a gradient, however, spectroscopic constraints are needed, together with additional tests (both empirical and theoretical) of the mass determination using seismology. In this context, we will report on ongoing tests of seismic scaling relations against independent measurements of masses and radii of nearby giants, and of giants belonging to old-open clusters observed by Kepler.
