We consider the effect of free -streaming axion emission on numerical
models for the cooling of the newly born neutron star associated with
SN1987A. We find that for an axion mass of greater than -10-3 eV, axion
emission shortens the duration of the expected neutrino burst so significantly
that it would be inconsistent with the neutrino observations made by the
Kamiokande II (KII) and Irvine -Michigan- Brookhaven (IMB) detectors.
However, we have not investigated the possibility that axion trapping (which
should occur for masses 20.02 eV) sufficiently reduces axion emission so that
axion masses greater than -2 eV would be consistent with the neutrino
observations.
