Possible Bridge: Radiation Hydrodynamic with Variable Eddington Tensor in Stellar Wind and Shock Breakout

[ Poster ]

Wun-Yi Chen (NTU, ASIAA);Ken Chen (ASIAA)

Observations and theories need bridges to connect, either from radiation to density distribution or vice versa. From simulations' point of view, radiation transfer is not only important in fitting observations but actually capturing realistic behavior of scattering, absorption, and heating/cooling, which then effect the final results of universe structures. We implement Variable Eddington Tensor developed by ATHENA group to calculate radiation transfer in various environments. We focus on the process where radiation starts to impact CSM or ISM, pre-modeling of molecular cloud to main sequence star/ red supergiant are done by Sung-Han and Po-Sheng using MESA code.
