First polarimetric observations and modeling of the FeH F^4 Delta-X^4 Delta system
N. Afram, S. V. Berdyugina, D. M. Fluri +3
Lines of diatomic molecules are more temperature and pressure sensitive than atomic lines, which makes them ideal tools for studying cool stellar atmospheres an internal structure…
First polarimetric measurements and modeling of the Paschen-Back effect in CaH transitions
S. V. Berdyugina, D. M. Fluri, R. Ramelli +3
We report the first spectropolarimetric observations and modeling of CaH transitions in sunspots. We have detected strong polarization signals in many CaH lines from the A-X system…
Absence of linear polarization in Halpha emission of solar flares
M. Bianda, A. O. Benz, J. O. Stenflo +2
High sensitivity observations of Halpha polarization of 30 flares of different sizes and disk positions are reported. Both filter and spectrographic techniques have been used. The…
He-D3 Polarization observed in Prominences
Renzo Ramelli, Michele Bianda
Spectro-polarimetric measurements of the D3-HeI 5876 A line profile in 35 prominences have been performed in 2003 with the Gregory-Coudé Telescope in Locarno. Two different experim…
