  • Abstract: This is a program to support simultaneous Rossiter–McLaughlin (RM) ground based observations of Neptune size planets with CHEOPS high precision photometry acquired contemporary to RV measurements. The history of the planetary system can be constrained by the measurement of the spin-orbit alignment. The combined sets of photometric and spectroscopic data make it possible in principle to break degeneracies among size, position, and temperature contrast of stellar active regions and derive with high precision the system parameters (see, e.g., the case of HD 189733 in Triaud 2009).

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.
