Detection of the tidal deformation of WASP-103b at 3 sigma with CHEOPS. (2022)

Abstract:Ultra-short period planets undergo strong tidal interactions with their host star which lead to planet deformation and orbital tidal decay. WASP-103b is the exoplanet with the highest expected deformation signature in its transit light curve and one of the shortest expected spiral-in times. Measuring the tidal deformation of the planet would allow us to estimate the second degree fluid Love number and gain insight into the planet's internal structure. Moreover, measuring the tidal decay timescale would allow us to estimate the stellar tidal quality factor, which is key to constraining stellar physics. ...(more)

We present the 12 transit light curves of WASP-103 obtained with the CHEOPS satellite. We give the reduced raw light curves and the detrended light curves. The images and the reduced original data can be obtained from DACE and the CHEOPS public archive.
