Notes

Identified as one of the most luminous X-ray sources in M31. Chiosi et al. (2014) suspected its symbiotic nature but failed to identify the optical counterpart consistent with such classification. On the other hand, it can be a short-period binary or AM CVn-type object too. Interesting is the detection of the 217.7s period (Trudolyubov & Priedhorsky, 2008) in X-ray data with no definite explanation (Chiosi et al. , 2014).
