Suspected of being a symbiotic star by Kenyon (1986), the system exhibits characteristics such as an M giant continuum, UV excess, and emission lines with low ionization potential (van Genderen et al., 1974; van Genderen, 1979,Schulte-Ladbeck, 1988). Eclipses have been observed in the system (van Genderen et al., 1974; van Genderen, 1979). The symbiotic nature is further supported by the analysis presented in Akras et al. (2019).
