Modeling the scattering polarization of the solar Ca i 4227 Å line with angle-dependent partial frequency redistribution
Gioele Janett, Ernest Alsina Ballester, Nuno Guerreiro +4
Context. The correct modeling of the scattering polarization signals observed in several strong resonance lines requires taking partial frequency redistribution (PRD) phenomena int…
Mapping Solar Magnetic Fields from the Photosphere to the Base of the Corona
Ryohko Ishikawa, Javier Trujillo Bueno, Tanausu del Pino Aleman +25
Routine ultraviolet imaging of the Sun's upper atmosphere shows the spectacular manifestation of solar activity; yet we remain blind to its main driver, the magnetic field. Here we…
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…
Magnetic sensitivity in the wing scattering polarization signals of the hydrogen Lyman-alpha line of the solar disk radiation
Ernest Alsina Ballester, Luca Belluzzi, Javier Trujillo Bueno
The linear polarization produced by scattering processes in the hydrogen Lyman alpha line of the solar disk radiation is a key observable for probing the chromosphere-corona transi…
