DKIST resolves sub-arcsec photospheric scattering polarization
Franziska Zeuner, Luca Belluzzi, Ernest Alsina Ballester +4
Scattering polarization signals offer a unique diagnostics of the physical conditions in the solar atmosphere, in particular magnetic fields via the Hanle effect. However, their sp…

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…
