HR diagram for seven StarTrack stellar tracks simulated with our R_MAX prescription for Z = 0.5 Z_⊙ (left panel) and Z= Z_⊙ (right panel). The initial masses are shown above their respective stellar tracks. The grey lines represent how the stars would evolve without limiting their expansion with our new radial prescription. The cyan area represents the area of the HR diagram beyond the HD limit. Despite the differences between M0 and M0_RMAX, in every case with M_ZAMS≳40 M_⊙, the R_MAX limit to stellar expansion only takes place in our models when the stars are already in the LBV regime (which means that, according to our wind prescription, the wind mass loss does not change) or for relatively short periods of time that do not significantly impact the final properties of COs.
