Notes

The star has been suspected of being symbiotic, as indicated by Neugent et al. (2019). The spectrum closely resembles that of the symbiotic star V3929 Sgr. However, the high luminosity of the object is more typical for red supergiants. Therefore, the authors proposed that the star is a high-mass symbiotic system (RSG+OB companion). It was previously identified as a possible RV Tau star (their object V2285) by Mochejska et al. (1999).
