The various techniques used in the visible and near-infrared for the measurement of intrinsic polarization coming from solar regions are described. Their...

Polarimetry provides key physical information on the properties of interacting binary systems, sometimes difficult to obtain by any other type of observation...

The observations were carried out using the five-channel photopolarimeter of the Torino Astronomical Observatory attached to the 2.15m telescope at the Complejo...

A brief description of the new 1.5-meter solar telescope GREGOR located at the Observatorio del Teide in Tenerife will be given. GREGOR will provide a spatial...

Polarized light provides key information on the physical conditions and geometry of astrophysical plasmas otherwise unattainable via conventional spectroscopy...

In a typical young open cluster the polarimetric data shows, for normal stars, that the distribution of angles of the polarization vectors can be describe by a...

Polarization of solar lines arises due to illumination of radiating atom by anisotropic (limb darkened/brightened) radiation. Modelling the polarized spectra of...

L-type brown dwarfs (Teff = 1400-2100K) are known for their dusty photospheres. Brown dwarfs may have asymmetric surfaces arising from rotationally-induced...
