The Milky Way stellar disk shows a broken radial density profile with four components, azimuthal dependence, inner and outer flaring, and a density-metallicity bump possibly from radial migration.
FIRE-2 simulations show that stellar radial redistribution scatter saturates at ~2 kpc for stars older than ~3 Gyr, with net orbital changes depending on age and current radius, broadly matching Milky Way observations.
Axisymmetric self-consistent models fitted to NSD kinematic data yield a mass of 1.05 x 10^9 solar masses, radial scale length ~89 pc, vertical scale ~28 pc, and declining velocity dispersion.
