Fig. B.3

Evolution as a function of time of the ratio of the surface angular velocity to the orbital velocity for a 15 M⊙ model at Z = 0.014 with an initial rotation of 135 km s-1 and with an orbital period of 1.4 days. The solid lower curve corresponds to a model without magnetic fields and the dashed upper curve corresponds to a model with an internal magnetic field.
