AST-0504947 Burrows, Adam University of Arizona Multi-Dimensional Simulations of Core-Collapse Supernovae ABSTRACT Recently developed fully 2D multi-group, multi-angle radiation/hydrodynamics codes will be used to investigate the roles of progenitor rotation, aspherical neutrino emissions, hydrodynamic instabilities, and initial mass on neutrino driven mechanisms of core collapse supernovae. The need for this work is motivated by the significant uncertainties in the process by which such supernovae explode (e.g., how is the stalled shock revived?). Special attention will be paid to the role of rotation and anisotropic neutrino heating on the viability of the supernova explosion. Beyond this, several other aspects will also be explored including: resulting iron distributions, the degree of top-bottom asymmetry, different treatments/coding of the underlying physics, neutrino and gravitational wave signatures, and pulsar kick mechanisms. The work here will directly contribute to the training of two graduate students, as well as improve our understanding of these important and complex events.
