  • Title of programme: Stellar Occultation by Minor Bodies in our Solar System with CHEOPS
  • Abstract: Stellar Occultation is one of the leading techniques in accessing important physical characteristics of solar system bodies. With it, it was possible to discover rings around the Centaur Chariklo and the TNOs Haumea and Quaoar, detect sub-km TNOs, and variations of Plutos atmospheric pressure. The knowledge of such characteristics has been important in understanding the origin and evolution of the solar system. Since the technique translates photometric resolution into astrometric resolution, a better photometric condition will provide improved constraints in the determination of the bodys physical characteristics. As a natural step forward, observing stellar occultation by spacecraft will provide better photometric circumstances avoiding the noise caused by atmospheric fluctuations. With CHEOPS, fourteen interesting stellar occultations have considerable chances of being observed, involving the dwarf planet Pluto and other TNOs larger than 500 km in diameter, including Quaoar, which has a known ring system. We can further study the atmosphere of Pluto, the rings of Quaoar, and improve our knowledge about the presence of rings or materials around these distant bodies.

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.
