Nitrogen surface abundance as a function of time for models with different rotational velocities for 10 M⊙ (green), 13 M⊙ (blue), 20 M⊙ (black) and 40 M⊙ (red) are shown. The model calculations have been ended shortly after the end of core hydrogen burning. The ZAMS velocities are indicated next to each track.
