„Hierarchical formation of the Milky Way”

dr Tadafumi Matsuno
Nicolaus Copernicus Astronomical Center, Toruń

Abstract:
Like other galaxies in the Universe, the Milky Way has formed and evolved through hierarchical structure formation. Stars serve as fossil records of this process: their dynamics retain information about where they come from, while their chemical abundances provide clues to the environments in which they formed. In this talk, I will review the current status of chemo-dynamical studies of the Milky Way and what they have revealed about its formation history. I will then discuss the next generation of spectroscopic surveys, which will soon provide unprecedented amounts of stellar chemical abundance data. Finally, I will present preliminary results from 4MOST, one of these new surveys, based on its science verification observations.
