Fraction of output snapshots when individual stars accrete mass as isolated single stars without any neighboring star within a radial distance of 2 × 10⁴ au and total number of output snapshots when accretion is ongoing $\frac{n_{\text{single }}}{n_{\text{single }}+n_{\text{mult }}}$ over final stellar mass (top). Each filled circle represents one of the 124 stars that have reached an age of at least 974 kyr. Light blue corresponds to 41 stars with M_* < 0.2 M_⊙, orange to 41 stars in the range 0.2 M_⊙ ≤ M_* < 0.8 M_⊙, green to 21 stars in the range 0.8 M_⊙ ≤ M_* < 1.6 M_⊙, dark-red to 7 stars in the range 1.6 M_⊙ ≤ M_* < 3 M_⊙, purple to 7 stars in the range 3 M_⊙ ≤ M_* < 5 M_⊙, brown to 2 stars in the range 5 M_⊙ ≤ M_* < 8 M_⊙, and violet to 5 stars with M_* > 8 M_⊙. The red squares correspond to the median per bin, the dark-blue horizontal lines show the mean per bin. The grey dotted line shows the mean value of all stars and the light-grey line is the corresponding standard deviation. The light-blue dashed line shows the line fit based on all points using numpy’s polyfit function. Bottom panel gives the histogram of $\frac{n_{\text{single }}}{n_{\text{single }}+n_{\text{mult }}}$ for all 124 stars that have reached at least 974 kyr of age (light blue bars), 41 stars with a final stellar mass of M_*,final < 0.2 M_⊙ (brown-orange bars) and 83 stars with M_*,final > 0.2 M_⊙ (green bars).
