Title: Core-collapse Supernova Theory: Successes and Perspectives
Supernova explosions terminate the lives of massive stars, produce and disseminate a major fraction of the heavy elements, and give birth to neutron stars and black holes. Their explosions can be triggered by energy transfer through neutrino heating, magnetorotational effects, or a hadron-quark phase transition in high-mass neutron stars, which tap the thermal, rotational, or gravitational energy reservoir of the new-born compact remnant. Recent 3D simulations have confirmed the viability of these mechanisms and, in particular, have shown that neutrino-driven explosions can explain the morphological and chemical asymmetries observed in supernovae, supernova remnants, and in the form of neutron star kicks. The talk will review these results with a special eye on neutrinos and their diagnostic potential to reveal the dynamical processes and thermodynamic conditions in the supernova core. Frontiers of the field are connected to the problem of neutrino-flavor oscillations and the question which stellar populations explode by dint of an important role of rotation and magnetic fields.
