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…
Evidence for the two fluid scenario in solar prominences
Eberhard Wiehr, Götz Stellmacher, Michele Bianda
This paper presents observational evidence of the different dynamical behavior of neutral and ionized species in solar prominences. The analysis of a time-series of Sr II 4078 A an…
