A RADIATIVE-TRANSFER MODEL USING SPHERICAL GEOMETRY AND PARTIAL FREQUENCY REDISTRIBUTION

The proper analysis of resonance emissions requires the use of a radia tive transfer model to accurately simulate the scattering mechanisms. We describe a model that provides a solution to the radiative transfer equations by incorporating spherical geometry in a nonisothermal atmo sphere while also accounting for partial frequency redistribution (PFR ) during the scattering process. The sensitivity of the model is demon strated, and comparisons are made to existing radiative transport mode ls. Specific references are made toward applying this model to studyin g the resonance emissions of hydrogen and helium.
