Top: semi-major axis vs. eccentricity distribution of the transplanetary disk under the stirring effect of an embedded population of 1000 Pluto-mass bodies according to Levison et al. (2011). This snapshot of the distribution is taken after 300 My of evolution. Bottom: semi-major axis vs. eccentricity distribution of the scattered disk produced by the dispersal of the transplanetary disk by the giant planet instability according to Gomes et al. (2005). Here the snapshot of the scattered disk orbital distribution is taken 350 My after the beginning of the planet instability, when the scattered disk contains 5% of the original disk’s particles.
