Results from a search for periods around the orbital one in TESS 23 light curves. Left panels: Periodograms of the observed light curves of the TESS-23a (top panel) and TESS-23b (bottom panel) observations in the frequency range of 6–8 d⁻¹. The strongest peak corresponding to the negative (ν⁻) superhumps is labeled. The position of the ν_orb frequency is shown by the vertical dashed line. Right panels: TESS-23a (top panel) and TESS-23b (bottom panel) light curves folded with the period of the negative superhumps. The phase-binned light curves and their best sinusoid fits are also shown.
