Evolution of eccentricities a) and inclinations b) as a function of time for the innermost planet (black curve) and the most massive planet (red curve) of the system shown in Fig. 3. The effects of the dynamical friction are clearly visible for the most massive planet, which evolves beyond 2 AU, where the protoplanetary disk contains originally ~14 M_⊕ in planetesimals. In contrast, the innermost planet of the system never felt the dynamical friction effects during 200 Myr, which can be seen in the significantly high values of its eccentricities and inclinations. A color version of this figure is available in the electronic version of the journal.
