Astronomical Polarimetry
Ikeda et al.
We present the results of polarimetric observations of symbiotic stars, AG Dra, AG Peg, and Z And. We used a high-resolution echelle spectropolarimeter, LIPS (Ikeda et al. 2003), mounted on UH88 telescope. We obtained the intrinsic polarization profiles in H-alpha for all symbiotics. Based on a statistical analysis, we argue that the polarization profile of AG Dra is due to Raman scattering of Ly-beta, because the characteristics of the polarization H-alpha profile agrees well with those of the Raman-6830 line.
