Description
The radiative neutrino decay is shown to explain the hard X-ray energy spectrum (10 keV-200 keV) from SN 1987a, observed by Ginga and Kvant. After the outer expanding shell becomes transparent to the X-ray, the spectrum, in our picture, is nearly constant and directly reflects the dynamical mechanism of the neutrino emission and its subsequent decay
