Radial profiles for the density of hit-and-run remnants from υimp/υesc = 1.5 collisions between two mid 10 MJ clumps (the two remnants have the same profile due to symmetry). Only the gas with a density higher than 10−12 g cm−3 is displayed. The profile of the mid 10 MJ model is shown for reference. For each impact parameter the post-collision bound mass to total mass ratio is respectively 95.3%, 97.5% and 99.7% with the angular momentum of the remnant being 2.7%, 2% and 0.7% of the initial angular momentum of the collision, respectively. Head-on collisions essentially perturb the structure of the colliding clumps more than oblique collisions.
