On the Systematics of Core-Collapse Explosions
Abstract
Recent observations of supernovae, supernova remnants, and radio pulsars suggest that there are correlations between pulsar kicks and spins, infrared and gamma-ray line profiles, supernova polarizations, and ejecta debris fields. A framework is emerging in which explosion asymmetries play a central role. The new perspective meshes recent multi-dimensional theoretical investigations of the explosion mechanism with trends in Ni yields and explosion kinetic energies. These trends imply that the mass above which black holes form after collapse is 30 M and that supernova explosion energies may vary by as much as a factor of four. In addition, new neutrino-matter opacity calculations reveal that the inner cores of protoneutron stars are more transparent than hitherto suspected. This may have consequences for the delayed neutrino-driven mechanism of explosion itself.
