Observational insights into Sr I 4607 Ã scattering polarization with DKIST/ViSP
Franziska Zeuner, Ernest Alsina Ballester, Luca Belluzzi +4
Scattering polarization signals in the Sr I 4607 Ã spectral line are among the strongest originating from the solar photosphere, offering a powerful diagnostic of tangled magnetic…
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…
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…
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…
Multi-wavelength spectropolarimetric observations of AR13724 performed by GRIS
C. Quintero Noda, J. C. Trelles Arjona, T. del Pino Alemán +10
Multi-line spectropolarimetric observations allow for the simultaneous inference of the magnetic field at different layers of the solar atmosphere and provide insight into how thes…
Non-Local Thermodynamic Equilibrium inversions of the Si I 10827 A spectral line
C. Quintero Noda, N. G. Shchukina, A. Asensio Ramos +4
Inferring the coupling of different atmospheric layers requires observing spectral lines sensitive to the atmospheric parameters, particularly the magnetic field vector, at various…
