Rate of stellar wind mass loss as a function of evolutionary age for $M_{He}^{i} = 15 M_{⊙}$ $Mathematical equation: $ M_{\mathrm{He}}^{\mathrm{i}} = 15 \,M_{\odot} $$ models at Z = 0.02 with varying overshooting parameters. The red solid line is for f_ov = 0.01, the blue solid line is for f_ov = 0.027, the dash-dotted line is for f_ov = 0.02, and the dotted line is for f_ov = 0.0 (no overshooting). The pentagram indicates central He depletion.
