Effect of Dust Obscuration on the Emission Lines of RR Tel
We continue our investigation of the emitting region of the symbiotic nova RR Telescopii by analyzing the emission line fluxes from high quality AAT optical spectra obtained in 2000 and by comparing these with previous observations. The fading found in the recent spectra suggests increased circumstellar dust absorption in the stellar wind from the mira. Differing absorption of lines formed in different regions provides information on the geometry of the dust regions. The radii of the Fe II emitting region obtained by the SAC method have been corrected for dust obscuration.
