Final masses of planets (total mass M_P = M_c + M_env) as a function of formation distance r₀ and formation time t₀ in the disc. Planets that are below the dark blue line have reached pebble isolation mass and can accrete gas. All planets that are below the white line have M_c<M_env, indicating that they have undergone runaway gas accretion. The black lines indicate the final orbital distance r_f of the planet. The black bottom right corner of the plot corresponds to orbital distances which the pebble production line did not reach at the time t₀. This figure corresponds to Fig. 4 in Bitsch et al. (2015b).
