Fast and accurate approximation of the angle-averaged redistribution function for polarized radiation
A. Paganini, B. Hashemi, E. Alsina Ballester +1
Modeling spectral line profiles taking frequency redistribution effects into account is a notoriously challenging problem from the computational point of view, especially when pola…
Discovery of Scattering Polarization in the Hydrogen Lyman- Line of the Solar Disk Radiation
R. Kano, J. Trujillo Bueno, A. Winebarger +25
There is a thin transition region (TR) in the solar atmosphere where the temperature rises from 10,000 K in the chromosphere to millions of degrees in the corona. Little is known a…
Magnetic Imaging of the Outer Solar Atmosphere (MImOSA): Unlocking the driver of the dynamics in the upper solar atmosphere
H. Peter, E. Alsina Ballester, V. Andretta +20
The magnetic activity of the Sun directly impacts the Earth and human life. Likewise, other stars will have an impact on the habitability of planets orbiting these host stars. The…
A Statistical Inference Method for Interpreting the CLASP Observations
J. Stepan, J. Trujillo Bueno, L. Belluzzi +25
On 3rd September 2015, the Chromospheric Lyman-Alpha SpectroPolarimeter (CLASP) successfully measured the linear polarization produced by scattering processes in the hydrogen Lyman…
Magneto-optical effects in the scattering polarization wings of the Ca I resonance line at 4227 angstroms
E. Alsina Ballester, L. Belluzzi, J. Trujillo Bueno
The linear polarization pattern produced by scattering processes in the Ca I resonance line at 4227 angstroms is a valuable observable for probing the solar atmosphere. Via the Han…
Observations of the Joint Action of the Hanle and Zeeman Effects in the D2 Line of BaII
R. Ramelli, M. Bianda, J. Trujillo Bueno +2
We show a selection of high-sensitivity spectropolarimetric observations obtained over the last few years in the Ba II D2-line with the Zurich Imaging Polarimeter (ZIMPOL) attached…
