Abstract

The emission rate of the invisible axion due to electron-related processes is evaluated in detail at high temperatures (T∼20 MeV) and at high densities (ρ∼10¹⁴g cm^-3), relevant to the supernova explosion. If one properly treats relativistic kinematics, no useful bound on the Peccei-Quinn symmetry breaking scale (f_A) is obtained from SN1987A, contrary to the recent argument by others. A brief comment on the bound from the neutron-neutron axion bremsstrahlung process is also made.
