Mass segregation ratios Λ and masses of N_MST most massive stars. The three rows with two grouped plots correspond to the M4, M5, and M6 models. The following descriptions apply to the two plots in each row. Top: mass segregation ratio Λ over time for the N_MST most massive stars in each cluster. The vertical dotted white lines indicate the time of collapse, where R_rms reaches a minimum. The solid white lines correspond to the right vertical axis showing the stellar mass of the cluster. Bottom: mass of the N_MST^th most massive star in each cluster. The grey vertical lines indicate the formation of a new most-massive star (N_MST = 1). As these are often not in the core, the time of formation, particularly in M4, corresponds to a drop in the apparent mass segregation. Note that each cluster was run to ≈ 1.5 t_ff, leading to different absolute timescales.
