Asteroseismology for Galactic archaeology: bridging two fields,
Astronomy in Focus, as presented at the IAU XXIX General Assembly, 2015. Proceedings of the IAU, Vol. 29B, 2016


Asteroseismology has the capability of precisely determining stellar properties that would otherwise be inaccessible, such as radii, masses, and thus ages of field stars. When coupling this information with classical determinations of stellar parameters, such as metallicities, effective temperatures, and angular diameters, powerful new diagnostics for Galactic studies can be obtained. An overview of the ongoing Strömgren survey for Asteroseismology and Galactic Archaeology (SAGA) is presented, along with recent results using asteroseismology to investigate the vertical age structure of the Milky Way disc.

Key words: Galaxy: stellar content / Galaxy: disc / Galaxy: evolution / stars: fundamental parameters / stars: oscillations / surveys / techniques: photometric,
