Same as Fig. 2, but planets are allowed to migrate. The purple and red lines mark the final positions of the planets. Planets in between the lines marked with 0.1 and 0.3 AU have a final position between 0.1 and 0.3 AU. Most planets migrate into the inner edge of the disc at 0.1 AU. Planets forming exterior to the water ice line () first accrete water rich material, but then migrate inwards accreting mostly rocky material resulting in a low water ice fraction of the planet. This results in a composition gradient of the planets with respect to the water ice line.
