  • We firstly examine the possible roles of mass loss and mixing as a function of stellar masses. Then we review the present observational status about additional mixing processes in massive stars. Various evidences from main-sequence OB stars, from blue supergiants, from SN 1987A and from Wolf-Rayet stars are given in favour of a significant mixing in radiative zones of rapidly rotating massive stars. We also particularly examine the role of mass loss on the ratio Δ Y/Δ Z of the relative helium… CONTINUE READING
