Notes

In Guilbault et al. (2000), a study on the photometric variability of the star led to its classification as a possible symbiotic star. However, a subsequent spectroscopic analysis of the object by Merc et al. (2021) revealed no emission lines and no signs of the hot component in the ultraviolet. The authors claimed that the data are consistent with an alternative scenario of a single giant star.
