  • Title of programme: CHEOPS transits of a 100 Myr old super-Earth in AB Dor moving group
  • Abstract: Planets around bright, young stars are our best laboratories to sample planet evolution in real time. HIP94235b is a super-Earth sized planet candidate orbiting a Gmag=8.2 Sun-like star in the ~100 Myr old AB Doradus moving group, identified in the recent observations from the Transiting Exoplanet Survey Satellite. The planet lies near the evaporation boundary where there is a paucity of super-Earth sized planets around mature aged stars, and is the perfect planet to study atmospheric evaporation processes in-situ. We will use CHEOPS to observe two transits of HIP94235b. These observations are essential to validating the planet, and to refining its transit ephemeris to enable the future atmospheric observations. With only one sector of TESS observations available, and no future TESS visits planned, CHEOPS is the only facility suitable to observe the shallow transits of this important planetary system, and preserve its transit ephemeris for future studies.

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.
