The second approach, using different models, also draws on the strengths of different scientific talents. Spherical models have been the weapon of choice for replicating supernovae, but breaking spherical symmetry with convection and using three-dimensional models might just reveal the secrets of the supernova recipe which may involve neutrino heating, convection, rotation, and magnetic fields. Visualization scientists can offer help in putting these models together. The possible explanations for the supernova mystery have prompted a fresh look at theory. In this theory, the pressure of magnetic fields increases, making fluid in the center buoyant.
Density is lowered and bi-polar outflows break the star apart.
A third idea is that stars are obliterated by a combination of neutrino power and MHD effects. The challenge is figuring out how they explode. And even that won't complete the picture. Dr. Mezzacappa started this journey in graduate school, and still has lots of work ahead. While figuring out how massive stars die is a formidable task, Dr. Mezzacappa has an advantage in that he can capitalize on the strengths of ORNL and the UT Department of Physics and Astronomy.
