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…
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…
Reconstruction of the Sunspot Number Source Database and the 1947 Zurich Discontinuity
Frédéric Clette, Laure Lefèvre, Sabrina Bechet +2
The recalibration of the sunspot number series, the primary long-term record of the solar cycle, requires the recovery of the entire collection of raw sunspot counts collected by t…
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…
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…
