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…

Study of an active region prominence using spectropolarimetric data in the He I D3 multiplet
S. Esteban Pozuelo, A. Asensio Ramos, J. Trujillo Bueno +3
Prominences are cool overdensities of plasma supported by magnetic fields that levitate in the solar corona. The physical characterization of these structures is key for understand…
