Abstract:
We present the detection and analysis of the phase curve of KELT-1b at
optical wavelengths, analyzing data taken by the Transiting Exoplanet
Survey Satellite (TESS). 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.
