BVR observations of polarization parameters of stars in reflection nebulas
The observed polarizations of the nuclei of reflection nebulas and fieldstars in B, V, R filters are given. A connection has been found betweenthe direction of the polarization vector, the structure of thereflection nebula, and the shape of the cloud in which the nebula issituated. The direction of the plane of polarization for stars seenthrough the filamentary structure of a nebula is the same as thedirection of the filaments. Stars situated at the edges of clouds andchannels have direction of the polarization vector the same as theapparent boundary of the cloud.
