Left panel: velocity of ejected members at the time of ejection (blue asterisks for single objects, and red open circles for binaries) for a dense configuration from model A, with N_sys = 70, Q_i = 0.5, and R_Pl = 0.005 pc. Right panel: sparse configuration with N_sys = 20, Q_i = 0.5, and R_Pl = 0.3 pc. The half mass radius evolution is superimposed (thick line), as a footprint of the stellar density for both cases.
