Session 78 - Supernova Remnants.
Display session, Wednesday, January 17
North Banquet Hall, Convention Center
We present the results of numerical studies of supernova remnant evolution in the context of supernova effects on galactic and globular cluster evolution. The characteristics of a supernova remnant are dependent on the environment where the explosion occurs. In particular, we show that parameters such as density and metallicity of the environment significantly influence the evolution of the remnants, and thus change their effects on the global environment (e.g., globular clusters, galaxies) as thermal and kinetic energy sources.
We conducted our studies using a one-dimensional, explicit Lagrangian hydrodynamics code with a tensor form of the artificial viscosity for treating shocks. We implemented ionization and metallicity dependent cooling.
Global quantities such as the total kinetic and thermal energies, and the radial extent are calculated for a grid of models. Such quantities can easily be incorporated as input physics in the numerical modeling of galactic or globular cluster evolution.
