The assembly history and evolution of the Milky Way as seen through the lens of asteroseismic ages

Prof. Andrea Miglio , University of Bologna

Our understanding of the formation and evolution of the Milky Way is often blurred and biased by the lack of precise and accurate stellar ages. In this contribution I will present the ongoing efforts and recent results of the asterochronometry project (https://asterochronometry.eu/ [asterochronometry.eu]), which aims both at testing and improving our knowledge of stellar physics, and at determining precise and accurate ages of stars (to 10-15%) in the regions of the Galaxy sampled by Kepler, K2, CoRoT, and TESS. Examples of recent and ongoing work will include age-dating stars using data from the TESS mission and inferences on the ages of both Gaia-Enceladus and in-situ stars observed by Kepler. Finally, I will discuss the prospects for extending these studies to larger samples, and briefly present the science case for a future mission dedicated to asteroseismology of crowded fields. The Zoom session for this colloquium will be open-ended to allow further informal discussions, moderated by Prof. Miglio's host, Hans-Guenther Ludwig (hludwig@lsw.uni-heidelberg.de). zoom access code 69120
