Notes

This star is a significantly reddened S-type symbiotic binary, confirmed by the presence of the Raman-scattered O VI 6825 feature (Miszalski et al., 2013). Similar to other S-type symbiotics with late M-type red giants, the OGLE light curve is characterized by low-amplitude SR pulsations. Additionally, a longer orbital variation with a period of 1068.4 days appears to be present (Miszalski et al., 2013). The spectrum displays the Raman-scattered O VI feature, although without corresponding high-ionization features such as [O III] or [Fe VII].
