Effect of the gas removal on the planetary orbits in the case of outward migration. Top panel: semi-major axis evolution of Jupiter, Saturn, Uranus, and Neptune from simulation C4 prolonged (plain line), C4 with the mock gas evaporation phase (dashed line; corresponding to Fig. 5), and C5 (dotted line; corresponding to Fig. 6 before the mock evaporation phase). Bottom panel: eccentricity evolution of Jupiter and Saturn in the two C4 cases described in the top panel.
