Hertzsprung-Russel diagram for the new evolution models of this work (solid lines), compared with the models from Yusof et al. (2022, dashed lines). The empty, dark yellow, and dark cyan circles represent the end of the H-core, the beginning of the He-core, and the end of the He-core burning stages, respectively. The yellow shaded region corresponds to the zone beyond the Humphreys-Davidson limit, in which LBV stars are expected to be found (Humphreys et al. 2016).
