Notes

Initially classified as a symbiotic binary by Li et al. (2015) based on a spectrum revealing numerous emission lines, including Raman-scattered O VI lines. However, upon obtaining and analyzing additional data, Li et al. (2015) concluded that the initially claimed symbiotic spectrum was an artifact of problematic subtraction. The object, as per their findings, is not a symbiotic star nor a pulsating object; instead, their spectrum is consistent with a G8 IV star.
