A Search for Neutrino Bursts from Stellar Collapse
Abstract
Events with energies between 10 and 75 MeV collected with the HPW proton decay detector during 248 live days between May 1983 and October 1984 were analyzed, and a search was conducted for the clustering of the events in time which the neutrino burst from a type II supernova would produce. Using the model of Woosley et al. (1986) for the production of antineutrinos during a stellar collapse, no evidence for supermassive (100 or more solar masses) stellar collapse at a distance of less than 0.79 kiloparsecs is found with a 90 percent confidence level, and no evidence for massive (10 to 25 solar masses) stellar collapse within 18 kiloparsecs of the earth during this time is found.
