  • Title of programme: Axis 3 - Measuring Oblateness and rapid Rotation in Exoplanets (MORE)
  • Abstract: Planets can attain non-spherical shapes as a result of the forces acting upon them. Centrifugal forces due to rapid planetary rotation lead to an equatorial bulge referred to as oblateness. Saturn has the largest oblateness within the Solar system owing to its fast rotation and low density. Therefore, measuring the oblateness can provide information about the rotation rate of a planet and its interior structure which can in turn provide insight into the dynamical history of the planet. This program will leverage the precision of CHEOPS to probe for large oblateness indicative of super-rapid rotation rate in selected planets around bright stars.

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.
