Hertzsprung-Russel diagram showing the evolution of stellar tracks computed with the Ṁ_rdw, Ṁ_Γe, and Ṁ_L/M winds in blue, green, and pink, respectively. The models are shown with ZAMS masses of 300 M_⊙ (top), 200 M_⊙ (middle), and 150 M_⊙ (bottom). The data symbols and shaded gray area are the same as in Figure 1. The black crosses and dots indicate the model location at the TAMS and the start of CHeB. The diagonal dashed gray lines show constant stellar radii as labeled.
