Growth tracks for our nominal model. Jupiter (red line), Saturn (orange line), Uranus (green line) and Neptune (blue line) grow and migrate through the disc ending up in a more compact configuration compared to the current one. The solid lines indicate the core accretion phase, the dashed lines indicate the gas accretion phase.
