  • Title of programme: The TTVs of a compact planetary system around an early-type star with CHEOPS
  • Abstract: The planetary formation and evolution process around early type stars are poorly mapped. We propose to use CHEOPS to observe a benchmark multi-planetary system (TOI-5126) around a young F star. The system hosts a Neptune sized planet with a 5.46 day orbital period (TOI-5126.01), and a sub-Neptune on a 17.9 day orbit (TOI-5126.02). Further, there are potential Transit Timing Variations (TTVs) exhibited in the TESS data at the 5-minute level. We will use CHEOPS to validate the candidate TTV signals of TOI-5126.01, as well as put mass constraints on the planet. These observations are essential for the confirmation of the planetary nature of the TOI-5126 system, enabling future atmospheric characterization and density measurements.

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.
