  • Title of programme: Catching the Transit of a Long Period Planet to Support Future Atmospheric Characterisation
  • Abstract: Across the population of 5000 currently-known exoplanets, only a handful are transiting long-period worlds. Understanding the nature of these far-out planets is of the utmost importance, but their rareness, coupled with the scarcity of observational opportunities, creates challenges for detailed characterisation. Here we seek to utilise the excellent precision of CHEOPS to obtain crucial data of CoRoT-9 b, one of the best large, cool planets for atmospheric characterisation with JWST. We will capture only the sixth transit light curve of this planet to have ever been obtained. It is vital that the ephemerides of this planet are updated and, due to its long period (95 days) and transit time (8 hours), a space-based facility is required. Therefore, CHEOPS offers an exclusive opportunity to study this world and lay the foundations for future atmospheric characterisation. Only one transit of CoRoT-9 b is observable in 2022 with CHEOPS and, as it happens before the expected scheduling window of AO-3, the discretionary programme offers the sole chance for it to be observed.

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.
