Radiation Transport Through Super-Eddington Stellar Winds

Joyce A. Guzik, Chris Fryer, Todd J. Urbatsch and Stanley P. Owocki

We present results of simulations to assess the feasibility of modeling outflows from massive stars using the Los Alamos 3-D radiation hydrodynamics code Cassio developed for inertial confinement fusion (ICF) applications. We find that a 1-D stellar envelope simulation relaxes into hydrostatic equilibrium using com- puting resources that would make the simulation tractable in 2-D. We summarize next steps to include more physics fidelity and model the response to a large and abrupt energy deposition at the base of the envelope.
