Light curves of HD 133729 phased with pulsation period. (a)–(c): HIPPARCOS (a), ASAS (b), and WASP (c) light curves. (d) Phase-averaged TESS light curves in Sector 11 (green dots), Sector 38, 2-min cadence (red dots), and Sector 38, 20-s cadence (blue dots). For clarity, 5 ppt offsets were applied between the light curves. The 2-min cadence data are averaged in 0.005 phase intervals, and the 20-s cadence data are averaged in 0.002 phase intervals. Phase 0.0 corresponds to the time of maximum light.
