Evolution of the mass-loss rate Ṁ as a function of the mean effective temperature for a 15 M_⊙ ESTER 2D-model with Z = 0.02 and for ω_i = 0.5. The star evolves from left to right with a mean effective temperature approaching 30 kK at ZAMS, and kK at TAMS. The black curve corresponds to case of a non-rotating 15 M_⊙ star with Z = 0.02 for which the mass-loss rate has been calculated using Vink et al. (2001) prescription. The vertical dashed line marks the evolutionary time at which the star reaches a TWR. The vertical dotted line marks the transition between Phase 1 and 2.
