Number distribution of accreted mass ΔM_accr (bin size equal to 0.01  M_⊙) for selected accretors with the labelled masses, and Y_accr = 0.44. The quantity N^∗ corresponds to the number of objects that have accreted ΔM_accr mass (solid green lines for mMS objects, dotted blue lines for bMS objects), normalized to the actual number of either bMS or mMS stars, multiplied by a factor 100.
