Two-dimensional multilevel radiative transfer with standard partial frequency redistribution in isolated solar atmospheric structures.
Abstract
We have implemented standard partial frequency redistribution (PRD) in a two-dimensional multilevel non-LTE radiative transfer code. The Multilevel Accelerated Lambda Iteration (MALI) method is used. First, a numerical approach for treating standard PRD effects is described, as well as a simple method for treating an optically thick bound-free transition with MALI. Then, the method is validated in mono-dimensional geometry. Finally, preliminary results from two-dimensional radiative modelling of solar prominences are presented.
