Abstract
We study processes in which neutrinos can be generated as a possible source for the neutrion emission form neutron stars. In the high energy limit and in the range em< E< Mw the cross sention for ye→evv is analytically calculated. We also calculate the cross section for yy→vv in the noncommutative space. The obtained results in comparison with the cross section for yy→vv and yy→ yvv in the commutative space could be quite important in the astrophysics. As a result the cross section for yy→ vv in the noncommutative spaces, in the range =100-300Gev , is comparable with its counterpart in the commutative space.
