Fig. 7.
Orbits of stars migrated from the inner galaxy and have nearly circular orbits at the end of the simulation. Orbits are color-coded by time in Gyr; the dashed circles from inner to outer show a position of the OLR at 0.5, 2, and 7 Gyr. The color bar shows the time for orbits of stars and for the OLR in units of Gyr. Each frame box size is 16 kpc × 16 kpc.
