Gamma-Ray Bursts from Supernovae
The cosmological gamma-ray bursts (GRBs) are thought to emit their energy in gas moving toward Earth at nearly light speed. A popular class of models places the source of this outflow in the collapsing core of a massive star. Massive stars also have massive envelopes, which pose a barrier to the development of relativistic motion: a baryon-loading problem. I review several models for segregating energy from mass in the context of supernova-GRB models.
