A new neutrino-emission asymmetry in forming neutron stars

Janka, Hans-Thomas
„Stellare Astrophysik”
Neutron stars are born as extremely hot and dense objects at the centers of massive stars exploding as supernovae. They cool by intense emission of neutrinos. Three-dimensional supercomputer simulations at the very forefront of current modelling efforts reveal the stunning and unexpected possibility that this neutrino emission can develop a hemispheric (dipolar) asymmetry. If this new neutrino-hydrodynamical instability happens in nature, it will lead to a recoil acceleration of the neutron star and will have important consequences for the formation of chemical elements in stellar explosions.
