(a) TESS photometric observations of HR 7672 from Sectors 54 and 81. The KPF data were collected 3 days prior to the start of TESS Sector 81, resulting in near-simultaneous coverage. (b) Power spectrum of the TESS light curve. The vertical lines highlight the oscillation frequencies derived from the KPF RV data (Table 2).
