  • Title of programme: The First Young Jupiter Transit with CHEOPS
  • Abstract: We propose to observe a transit of recently discovered young warm Jupiter V1298 Tau b (Rp ~ 0.9 RJup). By measuring the transit duration, we will constrain its eccentricity, allowing us to test formation and migration scenarios at a very early system age (~23Myr) - high eccentricity would point to migration via planet-planet scattering, while low eccentricity would be indicative of slower orbital evolution or in situ formation. We will also constrain the bulk properties of its atmosphere, by estimating its scale height. Our observation will enable future detailed atmospheric studies via transit and secondary eclipse spectroscopy with HST, JWST, and ARIEL, as well as ground-based instruments. This is an opportunity for CHEOPS to lay the foundations of the characterization of transiting young warm gas giant planets as a new class, and contribute to our understanding of gas giant planet formation and evolution.

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.
