Notes

This object is frequently listed among symbiotic stars (e.g., Fernie, 1972; Allen, 1973; Walker, 1977; Taranova & Yudin, 1979; Hric et al., 1991; also in SIMBAD or GCVS). However, it is an interacting binary system comprising an M giant and an A main sequence star, currently in the first episode of mass transfer. While closely related to symbiotic stars, it does not entirely meet the criteria for classification as a symbiotic star. In Munari (2019), the system is designated as a "pre-symbiotic star." Detailed investigations of the system were presented in Welty & Wade (1995) and Blind et al. (2011).
