Time evolution of the mean disk size (thick orange curve) for all 180 simulations with N = 2500 and r_vir = 0.75 pc. The two dotted orange curves give the standard deviation below and above the mean distribution of disk sizes. The green curve (below the orange curve) gives the evolution of mean disk size for stars with a high value of 𝒮_sp. The blue curve (axis to the right, also in blue) gives the cumulative distribution of the number of supernovae in these simulations.
