Top: specific total torque evolution acting on planets (20 MEarth) embedded in discs with different disc masses. The planets embedded in the higher mass discs MDisc > 0.02 M⊙ are in the convective zone in the disc, so that the torque acting on the planet is very noisy compared to the low-mass discs. Bottom: radial torque density Γ(r) acting on the planet embedded in a disc with Mdisc = 0.04 M⊙ at different stages of the evolution.
