3D histograms showing the evolution of a) the number of systems in the core N₁; b) the number of massive stars in the core N₂; c) the number of systems in the halo N₃; d) the number of VLMOs inside a 2.6 pc radius N₄; e) the binary fraction in the core N₅; and f) the number of wide (separation greater than 50 AU) binaries N₆ as a function of time for model A and for the initial configuration {N_sys = 40, R_Pl = 0.05 pc, Q_i = 0.5}. The histogram density corresponds to the number of simulations (out of 200) that fall in a given bin. The dashed and solid red lines correspond to the observed value and the acceptable range respectively.
