  • Title of programme: Characterisation of TESS Multi-planet Circumbinary System
  • Abstract: Circumbinary planets orbit around both stars of a tight binary and offer unique insights into planetary formation and migration. Ascertaining the correct orbital parameters of these planets is crucial to correctly characterise them. The HD29037 eclipsing binary system has recently been preliminarily identified as the third ever multiplanetary circumbinary system with TESS. Four planetary transits have been identified so far, candidate planet b has shown 3 TESS transits with an orbital period of around 64 days, while candidate c has transited once. From this we have calculated three possible families of solutions for the system with periods for the outer planet c at either 150, 225, or 449 days. With CHEOPS observations we will be able to observe two secondary eclipses and one primary transit of the binary, two additional transits of planet b, and one possible transit of planet c. These observations will allow us to ascertain the true orbital parameters of the system, and aid in characterisation in collaboration with ground based radial velocity observations. Exact timing of the transits are key to measuring planet masses and for accurate dynamical solutions, this is essential before ARIEL and JWST observations. Precise timings will also be key to finding any additional planets in the system.

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.
