Abstract

There is now irrefutable observational evidence that long duration gamma-ray bursts (GRBs) are linked to Type Ic core collapse supernovae (SNe Ic). This association has resulted in a wide acceptance of the collapsar model to explain the origin of GRBs. The collapsar model requires three physical characteristics: 1.) a massive core, 2.) a hydrogen free stripped envelope, and 3.) rapid rotation. These three characteristics are present in a rapidly rotating Wolf-Rayet (WR) star.
