Stellar Collapse, Core-Collapse Supernovae, and the Formation of Stellar-Mass Black Holes

Core-collapse supernovae from massive stars are among the most energetic events in the universe. They liberate a mass-energy equivalent of ~15% of a solar mass in the collapse of their progenitor star's core. The majority (99%) of this energy is carried away by neutrinos, while (~1%) is transferred to the kinetic energy of the explosive outflow. A smaller, yet still tremendous amount of energy is emitted in electromagnetic and gravitational waves. Core-collapse supernovae are the birth sites of neutron stars and stellar-mass black holes; their explosions seed the universe with the ashes of nuclear burning from which planets form and life can spring. In this lecture, I review our current understanding of core-collapse supernovae and discuss recent progress made and insight gained from new multi-dimensional computational models. These models are yielding new predictions for the signature of core-collapse supernovae in neutrinos and gravitational waves and I delineate how their observation from the next nearby core collapse event can shed light onto this still mysterious phenomenon.
