TESS observation of HD 88986 in sector 21 in 2020 February. Top: normalized TESS PDC-SAP light curve of sector 21 (black dots) along with the best-fit trend (red curve) to the data. The green vertical lines represent the times of the spacecraft’s momentum dumps. Middle: normalized re-extracted light curve of sector 21 (black dots). See the text for more information. Bottom: final detrended light curve. The expected HD 88986 b transit event from SOPHIE+ RVs (Sect. 5.3), with 1 sigma uncertainties, is highlighted in blue, and a single transit event is found in the TESS photometric data within this region.
