Same as Fig. 8, but shows the difference in the pericenters between planetesimals and the planet instead of planetesimals’ eccentricity. The left and right columns show the cases with τ_ecc = 10³ P_orb,p and 10⁵ P_orb,p, respectively. The upper and lower panels show the snapshots when the planetary eccentricity is e_p = 0.1 and 0.81, respectively. The vertical dotted lines are the pericenter and apocenter of the planet.
