Inside-out growth and stellar migration in the Milky Way

Caption

Inside-out growth and stellar migration in the Milky Way: Inside the star-forming disc (within ~12 kpc), abundant cold gas fuels continuous star formation, producing young stars. Beyond this break radius, star formation drops sharply, and the outer regions are instead dominated by stars that formed in the inner disk and later migrated outward.
