Top plot: resonant groups after the early inward migration of the giant planets at t = 3 Myr. Vertical dashed lines indicate roughly the positions of the resonances and the solid black line delimits the asteroid belt region. Bottom plot: fate of the resonant populations after the instability of the giant planets with a characteristic time scale of τ = 0.5 Myr, at t ~ 150 Myr. The resonance positions and the asteroid belt region are shifted in the bottom plot because Jupiter migrated from 5.4 to 5.2 au.
