  • Title of programme: Two sub-Neptunes in short orbit around two bright young G and K stars
  • Abstract: To understand the formation and evolution of planetary systems, there is a crucial need to map exoplanets parameters as a function of time. Young planetary systems are the most important to focus on, as they provide live snapshots of the processes at play and are currently dramatically under sampled. For planets discovered by survey mission such as the Transiting Exoplanet Survey Satellite (TESS), follow-ups required to characterise planetary orbits and atmospheres are only possible with a precise knowledge of the planets transit times. Thanks to CHEOPS, we will be able to refine the transit time ephemerides of two sub Neptunes less than 500 Myr old and in short-orbit, TOI-5082 b and TOI-5169 b. Five years from now and for both planets, the transit mid-time uncertainty will shrink from ~2 hours when solely relying on TESS data to less than 10 minutes with CHEOPS observations.

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.
