Disk fraction as a function of time obtained from our simulations taking t_th = 2.2 Myr (solid black line) for VLM stars and BDs, and assuming different mass accretion rate threshold time scales for VLM stars t_th,VLM = 2.2 Myr and for BDs t_th,BD = 3.2 Myr (black dash-dotted line). The coloured dashed lines are exponential decay laws expected from disk e-folding times 2.5 Myr (red line) and 5.5 Myr (blue line). The coloured dots are data for nine young nearby clusters, associations, and groups taken from Table 2.
