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…
Magnetic field diagnostics of prominences with the Mg II k line: 3D Stokes inversions versus traditional methods
Jiří Štěpán, Tanausú del Pino Alemán, Javier Trujillo Bueno
The Mg II k resonance line is commonly used for diagnosing the solar chromosphere. We theoretically investigated its intensity and polarization in solar prominences, taking 3D radi…
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…
Spectropolarimetric observations of the solar atmosphere in the H 6563 Å line
J. Jaume Bestard, J. Trujillo Bueno, M. Bianda +2
We present novel spectropolarimetric observations of the hydrogen H line taken with the Zürich Imaging Polarimeter (ZIMPOL) at the Gregory Coudé Telescope of the Istituto Ricerc…
The effects of three-dimensional radiative transfer on the resonance polarization of the Ca I 4227 line
J. Jaume Bestard, J. Trujillo Bueno, J. Štěpán +1
The sizable linear polarization signals produced by the scattering of anisotropic radiation in the core of the Ca I 4227 line constitute an important observable for pr…
Three-dimensional simulations of scattering polarization and the Hanle effect in MHD chromospheric models
Jiří Štěpán
Scattering line polarization and the Hanle effect are among the most important mechanisms for diagnostics of the solar and stellar atmospheres. The fact that real stellar atmospher…
