Notes

Suspected of symbiotic nature by Masetti et al. (2011) based on X-ray emission, the optical counterpart of this object is identified as a carbon star. Despite attempts using Swift, the star was not detected in UV or X-rays. However, in Yungelson et al. (2019), there is a misattribution to the paper by Masetti et al. (2011), inaccurately stating an orbital period of 151 days for the star, when it is actually referenced as a pulsational period of the star in the original paper.
