Supernova neutrino burst

Neutrinos are fermions, i.e. elementary particles with a spin of 1/2. They interact only through weak interaction and gravity. A core-collapse supernova emits a burst of ~ neutrinos and antineutrinos on a time scale of tens of seconds. Supernova neutrinos carry away about 99% of the gravitational energy of the dying star in the form of kinetic energy. Energy is divided roughly equally between the three flavors of neutrinos and three flavors of antineutrinos. Their average energy is of the o… Web12 ott 2024 · While many supernova models offer predictions of neutrino emission for only the first second of the burst, the Livermore model (Totani et al. 1998) provides predictions up to 20 s. Until recently the Livermore model was the only simulation with predictions out to such long times.
