What Is A Supernova?

Space is cool! Science is fun! Join us to talk about different space and science topics. In this post, we explore what a supernova is. Mar 22, 2020 ... When a massive star runs out of fuel, it cools off. This causes the pressure to drop. Gravity wins out, and the star suddenly collapses. Imagine ... [ReadMore..]

Halo Modification of a Supernova Neutronization Neutrino Burst

Halo Modification Of A Supernova Neutronization Neutrino Burst

We give the first self-consistent calculation of the effect of the scattered neutrino halo on flavor evolution in supernovae. Our example case is an O-Ne-Mg core collapse supernova neutronization neutrino burst. We find that the addition of the halo neutrinos produces qualitative and quantitative changes in the final flavor states of neutrinos. We also find that the halo neutrinos produce a novel distortion of the neutrino flavor swap. Our results provide strong motivation for tackling the full multidimensional and composition-dependent aspects of this problem in the future. Feb 5, 2013 ...
