Supernovae are one of nature’s most energetic “cosmic explosions”. But do we know how they work? Models based on the neutrino-driven mechanism have become increasingly sophisticated over the past 3 decades, and this mechanism still remains the leading explanation of the engine that drives supernovae. The leading alternate mechanism invokes magnetic fields. Unfortunately, energy constraints rule out this mechanism for the bulk of supernovae unless the current stellar progenitors are incorrect. Comparing these two mechanisms provides insight into the engines that power gamma-ray bursts (GRBs). The different geometry in black hole accretion disk GRB models allows many mechanisms which failed in core-collapse supernovae to work for GRBs. © 2000 American Institute of Physics.

    As we have heard at this meeting, it seems likely that GRBs originate in a very small fraction of stars that undergo a catastrophic energy release event toward the end of their evolution. Expressly, the association of some GRBs with supernovae has pointed a finger at deaths of massive stars as...

    Gamma-ray bursts (GRBs) are known to come in two duration classes, separated at ∼2 s. Long-duration bursts originate from star-forming regions in galaxies, have accompanying supernovae when these are near enough to observe and are probably caused by massive-star collapsars. Recent...

    Neutrino cross sections are important in many different astrophysical environments. Particularly needed is information about low energy (tens of MeV) cross sections. We review, for a few situations, the importance of neutrino cross sections for supernovae, gamma ray bursts and neutron stars.

    The article looks at the phenomenon of vanishing supernovae, noting that astronomers believe that half of known exploded stars are missing. Possible explanations include that the neutron star formed after a supernova collapsed into a black hole or is hidden from view by cosmic dust. Attempts to...

    If Gamma-ray Bursts (GRBs) are generally associated with supernovae, a relatively wide intrinsic luminosity function is implied. If it is assumed that the intrinsic luminosity function of GRBs is a power-law: &fgr;(L)∝L[sup -β], data from the BATSE 4B catalog can be used to constrain...

    We discuss the properties of the very energetic Type Ic supernovae (SNe Ic) 1998bw and 1997ef and Type IIn supernova (SN IIn) 1997cy. SNe Ic 1998bw and 1997ef are characterized by their large luminosity and the very broad spectral features. Their observed properties can be explained if they are...
