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…
