Abstract

We demonstrate the important role of anisotropic neutrino radiation on the mechanism of core-collapse supernova explosions. Through a newparameter study with a fixed radiation field of neutrinos, we show thatprolate explosions caused by globally anisotropic neutrino radiationrepresent the most effective mechanism of increasing the explosionenergy when the total neutrino luminosity is given. This is suggestive ofthe fact that the expanding materials of SN 1987A have a prolategeometry.
