Abstract:We present an application of the PALI (Polarized Approximate Lambda Iteration) method to the resonance scattering in spectral lines formed in the presence of weak magnetic fields. The method is based on an operator perturbation approach, and can efficiently give solutions for oriented vector magnetic fields in the solar atmosphere.
Keywords:Polarization  magnetic fields, radiative transfer  stars: atmospheres  methods: numerical
