Notes

The symbiotic nature of 2MASS J01113745-7159023 was noticed by Massay & Duffy (2001).  Its variability is similar to the variability observed in GX 1+4, a symbiotic X-ray binary. This suggested an enhanced mass-transfer during a periastron passage during orbital motion. This is particularly interesting because WD in 2MASS J01113745- 7159023 is among the hottest in SySt, which confirms high mass transfer rate in the system or a recent outburst (Iłkiewicz et al., 2018).
