Magnetic Field Stratification in Active-Region Plage from Ca II K and Ca II 8542 Å Spectropolarimetry
Iñigo Juanikorena Berasategi, Ernest Alsina Ballester, Javier Trujillo Bueno +31
We investigate the height variation of the line-of-sight (LOS) magnetic field in solar active-region (AR) plage from the upper photosphere to the upper chromosphere using co-spatia…
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…
Spectropolarimetric synthesis of forbidden lines in MHD models of coronal bright points
Ernest Alsina Ballester, Daniel Nóbrega-Siverio, Fernando Moreno-Insertis +1
The inference of the magnetic field vector from spectropolarimetric observations is crucial for understanding the physical processes governing the solar corona. We investigate whic…
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…
Accurate PRD modeling of the forward-scattering Hanle effect in the chromospheric CaI 4227 Å line
Luca Belluzzi, Simone Riva, Gioele Janett +7
Measurable linear scattering polarization signals have been predicted and detected at the solar disk center in the core of chromospheric lines. These forward-scattering polarizatio…
