Suggested to be a possible symbiotic star based on detected X-ray radiation and a K giant counterpart, as discussed in Shaw et al. (2020). The authors claimed that the object is a bursting neutron star with a giant companion. If confirmed as a symbiotic binary, it would be the only known example of a symbiotic X-ray binary exhibiting X-ray bursts.
