Models with the LMC composition are shown in the same way as in Fig. 1. The initial masses are the following: 20 (magenta), 25 (blue), 30 (red), and 35 M_⊙ (black). Left panel: models computed with the Schwarzschild criterion, and the right one shows the models computed with the Ledoux criterion. The green line shows the non-rotating model of 20 M_⊙ with the Ledoux criterion, while other cases are rotating models with an initial rotation of 0.4 V_c.
