Notes

Suspected by Miszalski & Mikołajewska (2014) based on a PN-like spectrum and red 2MASS colors typical of D-type symbiotic stars (J-H and H-S both >= 2.0). The absence of a red giant in optical spectra raises the possibility of an alternative classification as a PN with a dusty Wolf–Rayet central star. Miszalski & Mikołajewska (2014) noted that such Wolf–Rayet central stars typically exhibit temperatures of 30kK, and they are unable to ionize the [Ar IV] and [Ar V] emission lines observed. These lines are more commonly found in D-type symbiotic stars than in PNe. The symbiotic nature is further supported by the analysis of infrared data by Akras et al. (2019).
