Normalized projected stellar surface density profile, Σ(R), of the simulated system at the final snapshot for a model with R_Pl=500 pc and r_frac = 100 pc. The solid black line shows the normalized surface density obtained from the simulation after projecting the normalization on the x−z plane. The dashed red line corresponds to a normalized projected Plummer profile with the same scale radius, shown for reference. No observational surface density profile is available for UMa II; therefore, the comparison is restricted to idealized models. The deviations from a Plummer profile indicate that this functional form does not provide an optimal description of the final stellar distribution in our simulations.
