Extended Data Fig. 5: Folded light curves of WD0032–317.
Normalised (grey dots) and binned (black error bars) light curves of the WD0032–317 system from LCOGT (left), WISE W1 band (top right; unbinned), and TESS (middle and bottom right), phase-folded over the orbital period (P = 8340.9090 s). No phase shift is seen between the various bands. The orbital period matches the one obtained from the spectroscopy. The error bars of the binned light curves show 1.48 times the median absolute deviation of the flux divided by the square root of the number of data points in each bin. A sine function fitted to orbital phases ∣φ∣> 0.2 is plotted in red. The residual plot for each model is shown in the sub-panel below each light curve. The illustrations on top demonstrate the system’s configuration at each orbital phase. The flat bottom corresponds to the companion’s night side.
