Same as Fig. 7, but for different eccentricities of the exterior planet (and for μ = 0.002 and τ₀ = 0.002). For the e_p > 0 cases, plots are presented for a passage of the planet at periastron and apoastron. Note that, since for these e_p > 0 cases the unstable chaotic region inside the planet’s orbit is much wider than when e_p = 0, the initial disc of parent bodies extended down to 25 AU for the e_p = 0.1 and e_p = 0.2 runs.
