A Two-stage Settling of the Milky Way Disk Revealed by Precise ChronoGal Ages
The spatial distribution of Galactic disk stars of different ages and metallicities encodes its dynamical evolution history and formation pathways. The lack of precise ages for large, representative samples of stars has traditionally been a drawback for securely differentiating among formation scenarios proposed to exp...
