  • Abstract: We propose observing two primary transit events of WASP-161b, using CHEOPS. WASP-161b is an already identified giant planet (Barkaoui et al. 2019). The TESS transit depth reveals an offset at the 2$\sigma$ level compared to the transit depth resulting from joint analysis of other multiwavelength data. The difference in the wavelength-dependent transit depth could either be due to atmospheric features, sampling rate distortions of the light curve, or due to errors in the derived limb darkening parameters. The high sampling rate and precision of the CHEOPS data will result in an accurate determination of these parameters. It will then be used as priors in the re-analysis of the previous light curves for a joint recharacterization of its atmosphere. The preferred observable mid-point times are two of 2022-01-04T, 2022-01-10T, 2021-12-25T, 2021-12-19T.

Mission Description CHEOPS (Benz et al., https://doi.org/10.1007/s10686-020-09679-4) is a European Space Agency (ESA) mission in partnership with Switzerland with important contributions to the payload and the ground segment from Austria, Belgium, France, Germany, Hungary, Italy, Portugal, Spain, Sweden and the United Kingdom.

The satellite has a single payload comprising an ultra-high precision photometer covering the 330 - 1100 nm wavelength range in a single photometric band. Observations are made as part of the Guaranteed Time Observing Programme that is formulated by the CHEOPS Science Team, and the Guest Observers Programme through which the Community at large can apply for CHEOPS time.
