Evolution of the equatorial velocity through the MS phase for 7 M_⊙ and 15 M_⊙ models. Continuous lines correspond to Z = 0.014, whereas dashed lines correspond to Z = 0.002. Different colours indicate different values of Ω / Ω_crit at the ZAMS: red corresponds to 0.43, green to 0.83, and magenta to our new models with a large angular momentum content.
