Validity of the CRD limit for modeling scattering polarization in the photospheric Sr I 4607 Å line
Simone Riva, Gioele Janett, Franziska Zeuner +3
Context. Scattering polarization in the Sr I 4607 Å line is a key diagnostic for small-scale, unresolved magnetic fields in the quiet solar photosphere, inaccessible to Zeeman-base…
Observational insights into Sr I 4607 Å scattering polarization with DKIST/ViSP
Franziska Zeuner, Ernest Alsina Ballester, Luca Belluzzi +4
Scattering polarization signals in the Sr I 4607 Å spectral line are among the strongest originating from the solar photosphere, offering a powerful diagnostic of tangled magnetic…
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…
Observation and Modeling of the circular polarization of the Cr I magnetic field induced transition at 533.03 nm
Hao Li, Tanausú del Pino Alemán, Javier Trujillo Bueno +1
We study the circular polarization of the magnetic field induced transition (MIT) between the and states of \ion{Cr}{1} at 533.03~nm…
