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…
Kilogauss magnetic fields from simulations of small-scale dynamo action in the convective envelope of a white dwarf
Fabio Riva, Tim Cunningham, Hans-Günter Ludwig +2
About 20% of white dwarfs are observed to host large-scale magnetic fields, but the origin of white dwarf magnetism remains uncertain. Small-scale turbulent dynamos (SSDs), which e…
ZIMPOL detects scattering polarization in He I D during a solar flare
Francesco Vitali, Andrea Francesco Battaglia, Luca Belluzzi +5
Spectropolarimetric observations of solar flares in the He I D line at 5876 Å are extremely rare, and their diagnostic potential remains largely unexplored. We report the first…
3D radiative transfer modeling of scattering polarization with partial frequency redistribution I. Verification and disk-center results for the solar Ca I 4227 Å 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…
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…
Diagnostic potential of wavelength-integrated scattering polarisation signals of the solar He II Ly-alpha line
F. Riva, G. Janett, L. Belluzzi
Aims: Main goal of this work is to study the potential of He II Ly-alpha wavelength-integrated scattering polarisation for probing the magnetism of the solar upper chromosphere. Me…
