| Abstract: |
Rotation is a key ingredient in making a gamma-ray burst during the death of a massive star. It may also play a role in ordinary supernovae, yet the necessary angular momentum is, in both cases, far greater than that of ordinary pulsars. We present models of presupernova evolution that include magnetic and non-magnetic modes of angular momentum transport and arrive at rotation rates, in the lighter stars (~10 - 15 MSolar), that are similar to those observed for the fastest, youngest pulsars. More massive stars and alternate, non-standard evolutionary paths may be necessary for GRBs. These are discussed, along with speculations regarding the final fate of η-Carina. |
