Snapshots of slices in the ɀ-direction from the simulation of a super-critical disruption between mid 10 and 5 M_J clumps with b = 0 and υ_imp/υ_esc = 2. The shock wave propagates in both clumps and accelerates the gas beyond the mutual escape velocity. The ejected material is very low in density and is distributed over ~100 AU (note the different length scale of each frame). This event clearly shows how the population of clumps can decrease as a result of a collision.
