Abstract (from CDS):

We carried out polarimetric observations of two symbiotic stars, AG Dra and Z And, using the Line Polarimeter and Spectrograph (LIPS), a high-resolution echelle spectropolarimeter. We obtained the intrinsic polarization profiles with a broad wing in Hα for both symbiotics. Based on statistical analysis, we argue that the polarization profile of AG Dra is due to Raman scattering of Lyβ, because the characteristics of the polarization Hα profile agrees well with those of the Raman λ6830 line.
