Supernova Simulations in Three Dimensions: Models Confronting Observations — •Hans-Thomas Janka — Max Planck Institute for Astrophysics, Garching, Germany

Recently the first self-consistent, three-dimensional computer simulations of supernova explosions of massive stars have become possible and reveal new, stunning phenomena like a dipolar emission asymmetry of electron neutrinos and antineutrinos. They lend support to the viability of the neutrino-driven explosion mechanism in principle, although stars above ten solar masses are hard to explode and might suggest still missing physics. The violent hydrodynamical instabilities that facilitate the onset of the explosion lead to kicks and spins of the newly formed neutron stars and to supernova asymmetries, whose observations can help to decipher the physics of the central engine.
