Mass versus semi-major axis diagram for a population of planets, assuming one planet grows in each disc. The colour code shows the fraction of rocky planetesimals accreted by the planet. Planets whose core is the result of the accretion of rocky planetesimals are in red, whereas planets whose core has been made by the accretion of icy planetesimals are in blue. The total number of point is 4936. Planets in the vertical line at 0.05 AU are planets that reached the inner boundary of the computed disc. If the computational domain were extended to lower semi-major axis, their fate is uncertain. They could continue migrating toward the central star and be accreted, or could stop their migration somewhere in the inner disc cavity.
