Scientific paper

The neutrino emissivity from e-e+ pair annihilation is calculated for a hot, nondegenerate plasma, T>>TF (TF is the electron degeneracy temperature), in a magnetic field B of arbitrary strength. The results are fitted by an analytic expression. A not-very-strong magnetic field, b=B/Bc<<1 (Bc=4.41×1013 G), enhances the emissivity of a nonrelativistic plasma, t=T/Tc<~b (Tc=6×109 K), and does not affect the emissivity at higher T. Stronger fields, b>>1, influence the pair annihilation if t<~ √b . At t>~b1/4 they suppress the process, and at t<
