  • Title of programme: Solving the orbital ambiguity of a new transiting circumbinary planet TIC 172900988-b
  • Abstract: One of the most exciting breakthroughs in the field of exoplanets was the discovery of circumbinary planets (CBPs). Only about a dozen were found, however, leaving a vast gap in our understanding of these fascinating worlds - similar to the state of the field 20 years ago when only a handful of hot Jupiters were known. Using a new detection technique we have developed - the occurrence of multiple transits during one conjunction - and data from TESS, we can detect an order of magnitude more CBPs. In addition to enchanting individual-case discoveries and their intriguing dynamics, this will enable deeper understanding of the formation and evolution of CBPs, and of their binary hosts. Here we propose to observe a new transiting CBP we recently detected in TESS data and break the degeneracy between four photodynamical solutions for the system. CHEOPS is uniquely-suited for the task due to the combination of precision photometry, instrument stability and duty cycle it offers.

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.
