  • Title of programme: Rescuing Longer Period TESS Planet Candidates for Future Atmospheric Characterisation
  • Abstract: Keeping track of the colossal number of new exoplanet detections is becoming ever more difficult. Yet, if we wish to conduct a thorough characterisation of these worlds, by studying its atmosphere for instance, we must be sure of when the planet is going to transit. Due to the short observing sectors of TESS (< 30 days), our knowledge of the ephemerides of these worlds is quickly decaying. In fact, by the time most planet confirmation papers are published the uncertainty on the transit time is often into the tens of minutes and, when followed-up, large shifts are often seen in the transit times. The situation is even worse for longer period planets, which are also more rarely found by the TESS mission. Hence, we propose to conduct timely observations of seven of the best longer period TESS planet candidates for atmospheric characterisation. These data will ensure that our knowledge of their ephemeris remains up-to-date and so will facilitate the possibility for atmospheric characterisation in the near-future. CHEOPS is the only facility capable of these observations and the dataset proposed will be of great value to the exoplanet community.

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.
