Monte Carlo sampling plot of the final planet mass vs. the semi-major axis, with the ice line planet formation model (Scenario A) on the left, the log-uniform distributed planet formation model (Scenario B) on the right, the self-gravitating disks (γ = 1) at the top and the non-self-gravitating disks (γ ≠ 1) at the bottom. The color corresponds to the (sub)stellar mass. Scenario A only produces close-in planets, while planets formed in Scenario B have a wide range of orbital distances. Growth and migration are more significant for the protoplanets around low-mass M-dwarfs than for those around brown dwarfs.
