Notes

Proposed as the first symbiotic star in a globular cluster, Henleywillis et al. (2018) based their assertion on observed X-ray emission. However, Belloni et al. (2020) countered this proposition, arguing that there is a superposition of two unrelated objects within the cluster - an X-ray source and a carbon giant. The carbon giant does not exhibit any emission lines in its spectra, challenging its classification as a symbiotic star.
