Abstract:
Scattering of solar limb darkened radiation field on atoms and molecules produces linearly polarized spectrum of the sun (Second Solar Spectrum). Partial frequency redistribution (PFR) plays a fundamental role in shaping the wings of linearly polarized profiles of strong resonance lines. Here we present the effects of the angle dependent (AD) PFR on resonance polarization both in the presence and absence of magnetic fields. We consider scattering on a two-level atom with unpolarized lower level, and a one dimensional isothermal atmosphere.
