Investigation of linear polarization of moustaches.
Abstract
A technique for the observation of the polarization of solar emission features in the H-alpha line is described. The technique makes it possible to obtain, in one exposure, a set of four polarized spectrograms of the same region of the sun for four positions of the linear-polarization analyzer axes which are separated by 45 deg. The proposed method can be used to determine all of the parameters of the linear polarization of emission. The results of the investigation of the emission polarization of moustaches in one active region are presented. The degree of polarization and its distribution along the H-alpha profile is determined as well as the azimuths of the moustache polarization plane.
