  • Title of programme: Validation of candidate TESS Neptune Desert Planets
  • Abstract: Over 1400 exoplanetary systems are known to host planets with orbital periods less than 5 days, however, there is a distinct lack of Neptune sized exoplanets (radii from 3-10 R_Earth) at these short periods. Therefore, this region in parameter space is commonly referred to as the Neptune desert. It is not clear what mechanisms lead to the dearth of exoplanets in this region, though many theories have been put forward. it is thought to be caused by physical mechanisms at play during planet formation and/or evolution. With this program we propose to validate 9 planetary candidates identified by the Transiting Exoplanet Survey Satellite (TESS) which appear to lie in this Neptune desert. We will validate the planetary nature of all targets while also improving the radii measurements of 5 targets by 54-83%, and by doing so ascertain whether these candidate planets are indeed members of the Neptune desert.

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.
