Abstract
A numerical model of the transient behavior of a radiation-dominated shock was calculated in order to demonstrate the relatively large initial escape of internal energy that takes place when the opacity law is a positive power of temperature, as for neutrinos,K∼T 2. Attention was given to the consequences of diffusive transport of radiation versus local production of internal energy by duplicating the calculation with and without artificial viscosity. It is concluded that a shock formed on the neutron star core of an imploding supernova may radiate its internal energy in electron neutrinos more effectively than had hithertofore been considered.
