The impact of red-giant asteroseismology on Galactic Archaeology

This talk contains a review of the advances of Galactic archaeology in the last 10 years, with a particular focus on studies that have become possible thanks to ensemble asteroseismology with CoRoT, Kepler, K2, and TESS - in combination with Gaia and large ground-based spectroscopic surveys. Red-giant stars are particularly interesting for Galactic archaeology studies, since they are numerous, bright, and cover a wide range of stellar ages. Even in the PLATO era, red-giant ages derived from joint asteroseismic and spectroscopic constraints will only be available for select samples in certain fields. Therefore, Galactic archaeologists typically use the much larger coverage of spectroscopic surveys like APOGEE, GALAH, LAMOST, or Gaia RVS to make inferences about the Galactic past. However, whenever age becomes a crucial parameter, asteroseismology is needed to obtain meaningful results. The future for Galactic archaeology studies with PLATO (combined with the next Gaia data releases) is even brighter.
