Evolution of 40 M_⊙ rotating models with Z_LMC, α_ov = 0.1 and α_semi = 1.0 (orange), 0.1 (blue), 100 (red), and finally α_ov = 0.5 with α_semi = 1.0 (grey). Left: evolution of the effective temperature as a function of central He abundance, illustrating the fraction of core He-burning spent at RSG and BSG phases. Right: evolutionary tracks shown in an HRD, highlighting a variation of blue loops and RSG evolution.
