Evolution in time of the eccentricities a) and inclinations b) for the least massive planet (black curve) and for the most massive planet (red dashed curve) of S3 simulation for γ = 0.5. The dynamical friction phenomena is evident for the most massive planet, which does not exceed values of eccentricity and inclination of 0.12 and 3.15°. In contrast, the least massive planet reaches highest values of eccentricity and inclination of 0.35 and 13°. The color figure is only available in the electronic version.
