Overview

How a core collapse supernova successfully explodes is only partially understood. Computer models indicate that the accretion shock wave stalls around 200 km from the newly formed proto-neutron star. Despite the abundance of energy from the gravitational collapse and theories predicting how this energy might reenergize the accretion shock, simulations still fail to produce a robust explosion. Hydrodynamic models play an important role in this analysis. I will describe in detail the acoustic waves driven by the PNS and the dissipation of thermal energy by these waves into the critical Gain Region. Using the criteria laid out in the Janka model, I will then discuss the impact that this energy has on the restart mechanism. In addition, numerical issues associated with the hydrodynamic supernova model will be discussed.
