Abstract

The effects of partial frequency redistribution are implemented in the Polarized Accelerated Lambda Iteration (PALI) method of Faurobert-Scholl et al. (1997). The numerical scheme is an extension of the core-wing technique of Paletou & Auer (1995) originally developed for non-polarized line transfer problems. Using a new code, we validate theoretical results against those given by a Feautrier type code.

Key words: line: formation – polarization – radiative transfer – methods: numerical – stars: stmospheres
