  • Abstract: The origin of the high-density planets residing within the Neptune desert (a region of the planetary mass-period plane otherwise devoid of planets) is a major new mystery of the TESS era. In this programme, we propose to confirm an object that provides a direct origin story for the formation of objects within the desert. TOI-XXXX.01 is a high-mass Neptune and the most eccentric short-period planet candidate ever identified, which will migrate deep into the Neptune desert on a relatively short (less than 1 Gyr) timescale. It also has a stellar companion capable of driving past dynamical migration, and it resides exactly at the tidal disruption boundary for a Jupiter-sized object, suggesting that this planet is indeed the exposed interior of a would-be hot Jupiter. With 30 CHEOPS orbits, we can definitively confirm this system, precisely measure its density (placing it into context with other super-Neptunes in the desert), and independently validate its remarkably high eccentricity.

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.
