# Hanle effect with angle-dependent partial redistribution

@article{Nagendra2002HanleEW, title={Hanle effect with angle-dependent partial redistribution}, author={K. N. Nagendra and H{\'e}l{\`e}ne Frisch and Marianne Faurobert}, journal={Astronomy and Astrophysics}, year={2002}, volume={395}, pages={305-320} }

The polarized line transfer equation for the Hanle effect is solved in the framework of an exact partial frequency redistribution (PRD) theory developed by Bommier (1997a,b). In that theory the effect of collisions on the Hanle effect is con- sidered self-consistently. We follow that approach in the line transfer computations presented here. The theory formulated by Bommier clearly recognizes two levels of approximations for exact PRD, in order to facilitate the solution of the line transfer…

Selective absorption processes as the origin of puzzling spectral line polarization from the Sun

It is shown that the polarized light arises from selective absorption from the ground level of the triplet system of helium, and that the presence of magnetic fields of the order of a few gauss that are highly inclined with respect to the solar radius vector disproves the common belief that population imbalances in long-lived atomic levels are insignificant.
