As Fig. 4, eight time-snapshots of inclination versus semimajor axis of one of the nominal model simulations are shown. The black line roughly delimits the main belt region. At t = 2.31 Myr, t = 2.56 Myr, t = 2.70 Myr and t =2.70 Myr, Jupiter, Saturn, Uranus and Neptune (black filled dots) start to grow and to migrate inward and stop at t = 3 Myr. A fraction of bodies that were initially placed between 4 and 16 au, are injected in the asteroid belt region. Trojan asteroids are captured in the feeding zone of the planet’s cores and carried along during the migration. As can be noted, particles grouped in the resonance 3:2 (the Hilda asteroids at roughly 4 au), gain their inclination because of Saturn migrating towards Jupiter. A small population of centaurs orbits between Jupiter and Neptune.
