Abstract: |
Consideration is given to the possibility that single OBN-stars evolve from homogeneously mixed stars through rotationally induced mixing. It is found that a rotational velocity of at least 350 km/s is a precondition for the mixing. Thus, the equatorial velocity must spin down to this critical velocity to end the homogeneous evolution. Also, it is suggested that WN stars and the ejecta of LBV's might have undergone a homogeneously mixed phase. Possible scenarios for this transition are proposed. |
