Astronomy Colloquium - Victor Aguirre Borsen-Koch
Building the chronology of the Milky Way with pulsating stars
The field of Galactic archaeology has entered a golden. Large-scale spectroscopic surveys such as APOGEE are providing chemical abundances for millions of stars across the Galaxy, which is neatly complemented by stellar dynamics from the astrometric measurements of the Gaia mission. The missing piece needed to complete the puzzle of the formation and evolution of the Milky Way comes from stellar ages, which are challenging to determine by traditional techniques. In this talk I will review the progress made in this area thanks to the advent of asteroseismology as a tool for Galactic archaeology, and how pulsating stars can be used to date the chain of events that shaped our Galaxy into what it is today.
Speaker: Victor Aguirre Borsen-Koch, Aarhus University
