Study of an active region prominence using spectropolarimetric data in the He I D3 multiplet
S. Esteban Pozuelo, A. Asensio Ramos, J. Trujillo Bueno +3
Prominences are cool overdensities of plasma supported by magnetic fields that levitate in the solar corona. The physical characterization of these structures is key for understand…
Hanle rotation signatures in Sr I 4607 Å
Franziska Zeuner, Luca Belluzzi, Nuno Guerreiro +2
Observations of scattering polarization and the Hanle effect in various spectral lines are increasingly used to complement traditional solar magnetic field determination techniques…
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…
Velocity difference of ions and neutrals in solar prominences
Eberhard Wiehr, Goetz Stellmacher, Horst Balthasar +1
Marked velocity excesses of ions relative to neutrals are obtained from two time series of the neighboring emission lines He I 5015 and Fe II 5018 in a quiescent prominence. Their…
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…
