Notes

Included in the list of possible symbiotic stars or closely related objects in Munari & Zwitter (2002). Initially classified as a carbon star in Frogel et al. (1990), and as a carbon-rich AGB star in Boyer et al. (2011). Strong variability in V, I was detected by Soszyński et al. (2011) (long-term and short-term). In Raimondo et al. (2005), variability with a period of 2706 days was reported. Classified as a long-period variable in Mowlavi et al. (2018).
