Stellar tracks for a star of initial mass M = 20 M_⊙ at Z = 0.0025 for initial rotation speed Ω/Ω_c = 0.55 (left), 0.5 (middle), and 0.45 (right) and overshooting parameter f_ov = 0.03, 0.045, 0.07, and 0.1 (right panel) during the main sequence. The effect of overshooting is almost degenerate with that of rotation. A slight increase of f_ov corresponds to a reduction of the rotation threshold needed for self-stripping.
