MGAB-V1183: R This object is R (not R+E:). P=0.03497920(3) d from the ZTF data. Eclipse-like events in the older ZTF data were noises (no periodicity). No such events in the recent data.

[vsnet-chat 9137] NADA-V123: R
by Taichi Kato 13 Apr '22

13 Apr '22

NADA-V123: R Using TESS data, I obtained a very clear sinusoidal light curve with an amplitude of 0.15 mag. This object is not IBWD: but R. Detached WD+SD binaries below the period minimum are rare and this object needs to be studied in more detail.
