  • Title of programme: SoM - Simultaneous exoplanet observations with JWST
  • Abstract: JWST observations of exoplanet transits, occultations, and phase curves, can strongly benefit from simultaneous high-precision photometry in the optical. Advantages range from disentangling even minute stellar variability from the planetary signal to help characterise the exoplanet atmosphere, from e.g. the strong wavelength dependence of potentially time variable aerosol hazes. Since approved JWST programmes are scheduled well in advance, this synergy programme is designed to attempt simultaneous exoplanet observations with CHEOPS whenever possible. The total number of requested orbits is expected to be around 100 per year.

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.
