Mass accretion rate from 10%W_Hα (left panel) and EW_Hα (right panel) versus stellar mass. Diamonds and triangles represent Cha I and γ Vel stars, where filled and empty symbols refer to UVES and GIRAFFE data, respectively. Squares mark the position of the possible accretors. Big red diamonds represent the median values of Ṁ_acc for stellar masses of Cha I members binned at 0.2 M_⊙, where both confirmed and possible accretors were considered. The dashed line represents the relation, while the “noise boundaries” at 3 Myr and 10 Myr due to chromospheric activity are overplotted by dash-dotted lines (Manara et al. 2013). Mean error bars are overplotted in the right corners of both panels.
