Core-collapse supernovae: From neutrino-driven explosion models to observations

Theoretical Physics Colloquium by Prof. Hans-Thomas Janka. This presentation was held live on April 20, 2022 as part of the theoretical physics colloquium series hosted by Prof. Igor Shovkovy at the Arizona State University. The series features high-quality interactive presentations on current advances in theoretical physics by active researchers in the field of theoretical physics. Abstract for this presentation: Supernova explosions terminate the lives of massive stars, produce and disseminate a major fraction of the heavy elements, play an important role as neutrino and particle laboratory, and give birth to neutron stars and stellar-mass black holes, which have recently become sources of measured gravitational waves. After more than 50 years of progressively improved computational modeling, first-principle three-dimensional hydrodynamical simulations with detailed neutrino physics have meanwhile achieved to demonstrate the viability of the neutrino-driven mechanism. The consequences of this mechanism can now be confronted with observations. In particular, 3D simulations of such explosions provide new insights into the geometrical and chemical structure of young supernova remnants, possible explosion-progenitor connections, and the natal properties (masses, kicks, spins) of the compact objects formed in stellar core collapse events.
