Magnetic Field Stratification in Active-Region Plage from Ca II K and Ca II 8542 Ã Spectropolarimetry
Iñigo Juanikorena Berasategi, Ernest Alsina Ballester, Javier Trujillo Bueno +31
The study measures how the line‑of‑sight magnetic field strength changes from the photosphere to the upper chromosphere in solar active‑region plage using Ca II K and Ca II 8542 Å…
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…
