Evolutions of eccentricities, a), b), and inclinations, c), d), as a function of time for the innermost planet (black curve) and the most massive planet (red curve) of the S3 simulations and S3 simulations in the first and in the second set. The dynamical friction effects prevail over the larger bodies, which evolve in both sets of simulations in regions of the disk that are embedded in a swarm of planetesimals. A color figure is available in the electronic version.
