Burst of TeVγrays from SN 1987A: Cosmic storage rings?

Abstract
The JANZOS Collaboration has reported a 2-day burst of TeV γ rays from SN 1987 A 11 months after the explosion. At this supernova epoch TeV γ rays can only be produced by inelastic proton interactions and secondary π0 decay. The proton luminosity during the burst has to be 2×1039 ergs/s, in contradiction with the most recent estimates of the total power of an internal energy source. We suggest a burst model where the TeV γ-ray burst is produced by a previously accumulated proton beam, which is in agreement with the observed energetics of SN 1987A in all observation bands.
