Scientific paper

The first orbitally-resolved spectropolarimetric observations of the eclipsing nova-like variable RW Tri, obtained with the aim of testing the hypothesis that the absence of a deep eclipse in the Balmer emission lines is the result of disk emission scattered by a nonisotropic wind are presented. The data show linear polarization of order about 0.8 percent, which is largely independent of wavelength and binary phase. This polarization is attributable to scattering in the interstellar medium, and hence there is no evidence of electron-scattered light from RW Tri.
