Title : Talk 1: Why you should major in physics (talk on Wednesday or Friday to PHYS 111 and/or PHYS 211)
Talk 2: department seminar, Modeling Supernova explosions

Speaker : Dr. Wolfgang Bauer

Affiliation : Dept. of Physics and Astronomy, and the National Superconducting Cyclotron Laboratory, Michigan State University

Abstract :

It is generally believed that the abundances of heavy elements in our solar system are the result of an ancient supernova explosion. Therefore in order to understand the origin of the elements we need to understand the physics of supernova explosions. All conventional supernova modeling attempts are based on hydrodynamics. The first working three-dimensional codes are only now becoming available, but still nobody has solved the problem of coupling these simulations to a full Boltzmann transport simulation for the neutrinos. We propose a new approach based on coupled kinetic theory equations for neutrinos and baryons, which is an extension of methods developed for solving the transport problem in relativistic heavy ion collisions. First results of this new approach in 6-dimensional phase space will be shown.
