Notes

The symbiotic nature of 2MASS J01113745-7159023 was identified by Massey & Duffy (2001). Its variability is akin to the variability observed in GX 1+4, a symbiotic X-ray binary. This similarity in variability patterns suggests enhanced mass transfer during a periastron passage in the orbital motion. Notably, the WD in 2MASS J01113745-7159023 is among the hottest in symbiotic stars, indicating a high mass transfer rate in the system or a recent outburst (Iłkiewicz et al., 2018).
