Carter & Stewart PSJ 2020: Figure 4: Planetesimal disk eccentricity and inclination evolution and impact velocities during an example Grand Tack simulation with a 50 kyr evolution timescale and HG gas disk (GT15gm5e4_50k_hg1). Planetesimals are colored according to their average composition as a function of initial heliocentric distance of constituent material; (proto-)Jupiter and (proto-)Saturn are shown as grey circles. Body sizes are proportional to their mass. The light grey band indicates the present-day asteroid belt region.
