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…

Observation of the Molecular Zeeman Effect in the G band

A. Asensio Ramos, J. Trujillo Bueno, M. Bianda +2

Here we report on the first observational investigation of the Zeeman effect in the G band around 4305 A. Our spectropolarimetric observations of sunspots with the Zurich Imaging P…

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…
