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…

Magnetic field diagnostics of prominences with the Mg II k line: 3D Stokes inversions versus traditional methods
JiÅà ŠtÄpán, Tanausú del Pino Alemán, Javier Trujillo Bueno
The Mg II k resonance line is commonly used for diagnosing the solar chromosphere. We theoretically investigated its intensity and polarization in solar prominences, taking 3D radi…

Accurate PRD modeling of the forward-scattering Hanle effect in the chromospheric CaI 4227 Ã line
Luca Belluzzi, Simone Riva, Gioele Janett +7
Measurable linear scattering polarization signals have been predicted and detected at the solar disk center in the core of chromospheric lines. These forward-scattering polarizatio…
