Numerical methods in polarized line formation theory

Nagendra, K. N; Sampoorna, M (Astronomical Society of the Pacific, 2009-06)

We review some numerical methods and provide benchmark solutions for the polarized line formation theory with partial redistribution (PRD) in the presence of magnetic fields. The transfer equation remains non-axisymmetric ...
Phase matrices for higher multipoles of scattering in external magnetic fields

Oo, Y. Y; San, P. P; Sampoorna, M; Nagendra, K. N; Ramachandran, G (Astronomical Society of the Pacific, 2009-06)

Scattering phase matrices for forbidden lines are derived, in the presence of an external magnetic field, using the quantum electrodynamical approach. The particular case of 0 -> 2 -> 0 M2 transitions are considered and ...
Theory of polarized scattering in the mixed hanle-zeeman regime

Sampoorna, M; Nagendra, K. N; Stenflo, J. O (Astronomical Society of the Pacific, 2009-06)

We present the theory of polarized partial frequency redistribution (PRD) in the presence of arbitrary magnetic fields. Starting from the classical theory of Bommier & Stenflo (1999) we derive the laboratory frame PRD ...
