TESS photometry obtained for TIC 278659026. Top panel: entire light curve (amplitude is in percent of the mean brightness of the star) spanning 27.88 d sampled every 120 s. Gaps in this time series are due to the mid-sector interruption during data download and missing points removed from the light curve because of a non-optimal quality flag warning. Middle panel: expanded view of the light curve covering the first 9 days, where modulations due to pulsations are clearly visible. Bottom panel: LSP of the light curve up to the Nyquist frequency limit of the 2 min sampling rate (∼4467 μHz). The horizontal dotted line indicates 4 times the median noise level. Significant activity well above this threshold and in a frequency range corresponding to g-mode pulsations is clearly detected.
