  • Title of programme: Confirmation of the first planet to be associated with the Pleiades cluster
  • Abstract: The processes that drive planet formation and evolution within the first billion years are key in sculpting the planet population we observe today. Observing young planetary systems is the only opportunity to characterize these processes as they happen in real time. The Pleiades open cluster is one of the most well aged stellar groups, at 120 Myr making it the ideal parent population to anchor planet evolution models. We propose to use CHEOPS to observe two transits of the first planetary candidate, TOI-5358.01, kinematically affiliated with the Pleiades group. TOI-5358.01 is a mini-Neptune (P = 2.66 d, Rp = 2.754 Rearth), orbiting the young K4V star TOI-5358, originally discovered by TESS. CHEOPS observations are critical in the confirmation and characterization of the system, and will enable us to distinguish between different atmospheric characteristics, such as clouds and haze, in future transmission spectroscopy 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.
