  • Abstract: To uncover the demographics of exoplanet atmospheres, Ariel will require a large, diverse list of potential targets. Luckily, ground-based and space-based surveys have detected hundreds of transiting planets around bright stars. However, simply knowing of the planets existence is not enough and preliminary characterisation efforts must be undertaken to ensure the suitability of the target for study. A key piece of information is an accurate knowledge of the predicted transit time of a planet. In this programme, CHEOPS observations will be used to support the Ariel mission by maintaining the ephemeris of critical targets.

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.
