Results for the particle injection simulation that tests the scattering efficiency of a Jupiter analog (e = 0.05; top panel) compared with an enhanced eccentricity Jupiter (e = 0.23; bottom panel). For each panel, results are plotted for the percentage of particles that achieve periastron passages interior to the snow line (q = 2.7 au; solid line) and interior to an Earth orbit (q = 1.0 au; dotted line). The gray vertical dashed line indicates the semimajor axis of the giant planet.
