Abstract: (APS)
Axion emission from SN1987A by nucleon-nucleon axion bremsstrahlung is considered. On the basis of the neutrino observations the axion luminosity must be ≲1053 erg s−1. This occurs if (1) axions couple very weakly: ma≲0.75×10−3 eV; or (2) axions couple strongly enough to be ‘‘trapped’’ and radiated from an ‘‘axion sphere’’ with Ta≲8 MeV: ma≳2.2 eV. In general, ‘‘axion trapping’’ occurs for ma≳0.016 eV. Our mass constraints are at best reliable to within a factor of ≃3.
