  • Title of programme: Axis 1 - Uncovering a maverick population: CHEOPS observations of hot Jupiter systems with inner small companions (MAVERICK)
  • Abstract: Planetary systems hosting a hot or warm Jupiter (HJ/WJ) plus nearby small companion(s), such as WASP-47 (Nascimbeni et al. 2023), are extremely rare and very valuable to constrain formation and migration models. Only five such systems are known so far. Our goal is to increase the sample size by confirming and characterizing five TESS candidates with such an architecture, and improving their orbital/physical parameters including ephemeris, radii, and (when feasible) planetary masses through TTVs. As demonstrated by our work on WASP-47, RVs and TTVs are very synergistic at decoding these complex systems. A dedicated RV follow-up will be coordinated.

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.
