Left panel: evolution of R_h (solid lines) and the cluster total mass (dashed lines) for TD-MSP models with different numbers of 1P objects and 2P objects. Right panel: evolution of the ratio N₂/N_tot for TD-MSP models with different numbers of 1P objects and 2P objects. The global cluster parameters are listed at the top of each panel and are the same as for Figure 1. Note the sudden drop in R_h observed in this and the following figures. It is related to the dispersion of the cluster on the dynamical timescale as a result of the presence and energy generation by the BHS (Giersz et al. 2019).
