B., Madhusudhan N., Agol E., Antoci V., Poppenhaeger K. , Stassun K.G., Khalafinejad S., Tautvaisiene G. <Astron.

The light curve shows variations due to ellipsoidal variations, Doppler beaming, transit and secondary eclipse of KELT-1, and phase curve variations of KELT-1b. Description: TESS photometry of KELT-1 observed between 8 and 31 of October 2019, phase-folded by the orbital period of the brown dwarf companion KELT-1b, and binned. The flux variations are caused by ellipsoidal variation, Doppler beaming, transit and secondary eclipse and phase curve variations of KELT-1b.
