Final masses of planets that start with planetary seeds at r₀ and t₀ in a disc with Z_dust = 0.5% and a metallicity in pebbles of Z_peb = 1.0%. The blue, white and yellow lines have the same meaning as in Fig. 5 and the disc features a water-to-silicate ratio of 3:1. However, in contrast to the previous simulations, we have turned off the reduction of the migration speed in type-II migration due to the planet’s inertia.
