The polarization angle in the wings of Ca i 4227: A new observable for diagnosing unresolved photospheric magnetic fields
Emilia Capozzi, Ernest Alsina Ballester, Luca Belluzzi +1
When observed in quiet regions close to the solar limb, many strong resonance lines show conspicuous linear polarization signals, produced by scattering processes, with extended wi…
Observational indications of magneto-optical effects in the scattering polarization wings of the Ca I 4227 Å line
E. Capozzi, E. Alsina Ballester, L. Belluzzi +3
Several strong resonance lines, such as H I Ly-, Mg II k, Ca II K, Ca I 4227 Å\, which are characterized by deep and broad absorption profiles in the solar intensity spectrum, s…
Observations on spatial variations of the Sr~{\sc i} 4607~Å~scattering polarization signals at different limb distances with ZIMPOL
Sajal Kumar Dhara, Emilia Capozzi, Daniel Gisler +5
The Sr~{\sc i} 4607~Å spectral line shows one of the strongest scattering polarization signals in the visible solar spectrum. The amplitude of this polarization signal is expected…
Spatial variations of the SrI 4607Åscattering polarization signals at subgranular scale observed with ZIMPOL at GREGOR telescope
Sajal Kumar Dhara, Emilia Capozzi, Daniel Gisler +5
Sr I 4607Åspectral line shows one of the strongest scattering polarization signals in the visible solar spectrum. The amplitudes of these signals are expected to vary at granular s…
