Same as Fig. 5, but planets only migrate inwards. Planets can then start to grow exterior to the water ice line () and then migrate inwards resulting in a water ice gradient of the planets depending on their exact formation position in respect to the water ice line. Planets forming before 3–3.5 Myr all end up migrating to the inner edge at 0.1 AU (red/purple lines) in contrast to Fig. 5, because planet migration is only directed inwards. The final planetary masses though, are very similar to the previous simulations.
