Evolution of stellar mass as a function of time. Models within the Tayler-Spruit coupling scheme with MLT++ are shown for an initial rotational velocity of 300 km s⁻¹. The grey vertical line indicates the time when the first SN takes place. M_obs, max indicates the maximum stellar mass observable at that time. M_preCC, max is the highest pre-core collapse mass by the end of the evolution of all models. Green squares mark the TAMS and blue stars denote successfully reaching the C-TAMS phase. Top panel: our fiducial models. Middle panel: Reduced mass-loss rates over the entire evolution by a factor of 2. Note: this allows for the producion of SN progenitors with more than double the mass. Lower panel: Switching to the Nugis & Lamers (2002) rates instead of the Sander & Vink (2020) rates.
