Three Dimensions of Core Collapse

Three Dimensions of Core Collapse

The neutrino reheating mechanism works out in theory to trigger core-collapse supernovae, but we’ve had a lot of trouble getting it to work in 3-dimensional simulations. Because of the prohibitive computational expense, really accurate neutrino physics have thus far only been implemented in 2D. This paper seeks to investigate whether there are systematic differences in fluid behavior between 2D and 3D models in order to figure out whether a 2D model can really stand in for a 3D one.
