Abstract

A simplified analytic model of a cooling hot neutron star, motivated by detailed computer calculations, describes well the neutrinos detected from the recent supernova in the Large Magellanic Cloud. The observations do not require explanations that invoke exotic physics or complicated astrophysics. The parameters in this simple model are not severely constrained: 6.1 -3.6+3.5 × 1052 ergs emitted in electron antineutrinos, a peak temperature of 4.2-0.8+1.2 megaelectron volts, a radius of 27-15+17 kilometers, and a cooling time of 4.5-2.0+1.7 seconds.
