Abstract

Neutrino emission from the newly formed neutron star reduces the star's gravitational mass and thus reduces the depth of the gravitational potential well, out of which the mantle and envelope layers have to be pushed. We estimate that this effect can contribute ∼10% of the energy required for a Type II supernova explosion. It can thus facilitate the shock revival in the delayed-explosion scenario.
