Extended Data Fig. 4: Lomb-Scargle periodograms of TV Col.
From: Localized thermonuclear bursts from accreting magnetic white dwarfs
Periodograms using TESS data for TV Col a. Cycle 1 (120-s) low frequency periodogram. b. Cycle 1 high frequency periodogram. c. Cycle 3 (20-s) low frequency periodogram. d. Cycle 3 high frequency periodogram. In all panels the dashed-red lines mark the orbital frequency and associated harmonics, while the dashed-blue vertical lines mark the spin-to-orbital beat frequency. The dashed-magenta line marks the superorbital signal. The dashed-green lines mark the detected negative superhump, associated harmonics, and beats with the orbital frequency.
