Extended Data Fig. 5: Lomb-Scargle periodograms of EI UMa.
From: Localized thermonuclear bursts from accreting magnetic white dwarfs
Periodograms using TESS data for EI UMa during Cycle 2 (120-s cadence). a. Low frequency periodogram computed before the bursts. b. High-frequency periodogram computed before the bursts. c. Low-frequency periodogram computed after the bursts. d. High-frequency periodogram computed after the bursts. In all panels the dashed-red vertical line marks the detected orbital frequency. The dashed-blue vertical lines mark the spin-to-orbital beat frequency. The dashed-green line marks the positive superhump frequency.
