We study the broadband polarization of hydrogen lines produced by scattering of radiation, in the presence of isotropic electric fields. In this paper, we focus on two distinct problems: (a) the possibility of detecting the presence of turbulent electric fields by polarimetric methods and (b) the influence of such fields on the polarization due to

We report the identification of RXJ0636 as a new intermediate polar. The system's light curves and spectral analysis, together with a variety of its physical parameters are presented. A brief description of the observations leading to the above mentioned identification is also given.

We study the quiet Sun magnetic fields using spectropolarimetric observations of the infrared and visible Fe I lines at 6301.5, 6302.5, 15648, and 15653 Å. Magnetic field strengths and filling factors are inferred by the simultaneous fit of the observed Stokes profiles under the MISMA hypothesis. The observations cover an intranetwork region at the

We present preliminary results from the Open Cluster Polarimetric Survey. The aim of the survey is to provide clues about the characteristics of the dust responsible for extinction and polarization in the light from cluster members, about its spatial distribution and also about possible memberships. Our data on linear optical polarimetry were

The triple system HD158926 (λSco) has been observed interferometrically with the Sydney University Stellar Interferometer, and the elements of the wide orbit have been determined. These are significantly more accurate than the previous elements found spectroscopically. The inclination of the wide orbit is consistent with the inclination previously
