Upper panels: global mass-loss rates as a function of critical velocity fraction, ω, for 10 M_⊙ (left panel) and 20 M_⊙ models (right panel). Predictions of the local scheme, where surface mass flux is determined by Eq. (16) and the global mass-loss rate given by Eq. (11), are given in red. The standard scheme, where the mass loss rates are increased by Eq. (17) is depicted in black. All models have burnt 3% by mass of their initial hydrogen (i.e., X_c = 0.7169). Dotted lines represent mass-loss rates calculated from extrapolation (see Sect. 2.3). Lower panels: ratios of rotating star mass-loss to non-rotating star mass loss, , for each combination of mass-loss model and initial mass as given in each panel.
