Scientific paper

Virtually all proposed mechanisms for core-collapse supernovae are thought to involvethe formation of the shock wave near the edge of the homologous core, formed during the collapse of the iron core of a massive progentior star. The need for multi-dimensional modeling of the evolution of the shock wave has been widely recognized. In this poster we investigate the stability of this shock wave to local perturbations. Such an analysis is challenging since the shock is radiative by means of weak interactions coupling the matter to neutrinos. We futhermore attempt to delinate how shock wave perturbations affect the onset of convection during the prompt-shock era. Our poster presents both semi-analytic and numerical analyses of shock stability.
