Time evolution of the semi-major axis of the planet for the simulations corresponding to the case where the hybrid accretion of pebbles and planetesimals is considered. The black line corresponds to the fiducial simulation where type I migration recipes from Tanaka et al. (2002, T02) are adopted. The purple and green lines correspond to the cases where type I migration recipes from Paardekooper et al. (2011, P11) and Jiménez & Masset (2017, JM17) are considered, respectively.For the cases T02 and JM17, the planet remains in a migration trap until it opens a gap in the gas disk. The red line represents the values of the critical thermal mass associated to the thermal torque (for the T02 case). As this mass is always much lower than the mass of the planet, the thermal torque does not have any effect on the torque over the planet.
