Left panel: evolution of R_h (solid lines) and the cluster total mass (dashed lines) for TD-MSP models with different time of gas re-accretion (combination of t_delay = t_end time (100 or 50 Myr) and the fraction of t_delay time at which the gas re-accretion starts (t_start : 0.05 or 0.5)) Right panel: evolution of the ratio N₂/N_tot for TD-MSP models different time of gas re-accretion. The global cluster parameters are listed at the top of each panel and are the same as for Figure 1.
