  • Title of programme: Characterising the nearest known temperate Earth-sized exoplanet with CHEOPS
  • Abstract: In the study of exoplanets, special interest is often given to those most similar to Earth. Recent observations of a bright and nearby (12 pc) M-dwarf by TESS have revealed the presence of an Earth-sized exoplanet with a relatively low incident flux (no more than twice Earth's insolation). However, the unfortunate coincidence of the planetary orbital period with gaps in the TESS photometry means that there is a factor-of-two uncertainty in the orbital period. We propose CHEOPS observations to resolve this period ambiguity, and to more precisely characterise the physical parameters of the planet. Transit observations from CHEOPS will contribute significantly to our understanding of this system, and will form a key basis for current and future characterisation efforts of this remarkable planet.

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.
