Abstract
Scattering of the 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.
