Chemical Abundances and Orbits in the Milky way

In this project we will combine spectroscopic surveys (such as APOGEE) with GAIA astrometry to explore how chemical abundances of stars in the Milky Way (reflecting a common birth place/time) are related to their present-day orbits, and what it can teach us about the formation of the Galaxy. In the Galactic disk this will tells us directly how strong radial migration was, i.e. if the present-day orbit of a normal disk-star is related with its birth-orbit and address the fundamental question of how much "dynamical/orbit memory" disk galaxies retain.
