Evolutionary tracks of stars initially rotating with an equatorial velocity of ~ 100  km s^-1, with initial masses in the range 10 M_⊙...100 M_⊙, in the HR diagram (left), and in the g − T_eff diagram (right). The initial composition of the models is solar. The models up to 60 M_⊙ are published by Brott et al. (2011), while those of higher mass are unpublished additions with identical input physics.
