ZIMPOL detects scattering polarization in He I D during a solar flare
Francesco Vitali, Andrea Francesco Battaglia, Luca Belluzzi +5
Spectropolarimetric observations of solar flares in the He I D line at 5876 Ã are extremely rare, and their diagnostic potential remains largely unexplored. We report the first…

3D radiative transfer modeling of scattering polarization with partial frequency redistribution I. Verification and disk-center results for the solar Ca I 4227 Ã line
Pietro Benedusi, Simone Riva, Tanausú del Pino Alemán +6
Several strong solar resonance lines show observable linear scattering polarization signals, holding a great potential for investigating the magnetism of the outer solar atmosphere…

A numerical approach for modelling the polarisation signals of strong resonance lines with partial frequency redistribution. Numerical applications to two-term atoms and plane-parallel atmospheres
Fabio Riva, Gioele Janett, Luca Belluzzi +6
Aims. The main goal of this paper is to present an accurate and efficient numerical strategy for solving the radiative transfer problem for polarised radiation in strong resonance…
