Temporal evolution (in Myr) of the supernova progenitors of ZAMS 20 M_⊙ (dotted red line) and 35 M_⊙ (solid blue line) considered in our study. The panels display the stellar mass M_⋆ (panel a, in M_⊙), radius R_⋆ (panel b, in R_⊙), effective temperature T_eff (panel c, in K), angular frequency at the surface Ω_⋆ (panel d, in Hz), mass-loss rate Ṁ (panel e, in M_⊙ yr⁻¹), wind velocity v_w (panel f, in km s⁻¹), equatorial rotation velocity v_rot (panel g, in km s⁻¹), and the magnetic field in the wind at 0.02 pc B_⋆ (panel h, in µG).
