  • Title of programme: Investigating Sub-Saturns through CHEOPS Observations: Envelope-Rich K2-19b and Envelope-Poor K2-19c
  • Abstract: With more than 5000 discovered exoplanets, the field of exoplanet research has entered it is a completely new era in which exotic planets – whose properties may be rare but which reveal important astrophysical processes – could be studied in detail through the combination of long-term observations by ground-based and space telescopes. The sub-Saturn planets K2-19b and K2-19c are exemplary cases for detailed study by CHEOPS in that they pose a challenge to the standard planet formation model of core-nucleated accretion. Here we propose to use CHEOPS to observe transits of K2-19b and K2-19c to use the TTV technique to further improve the mass measurements of these interesting planets with the goals on (1) studying the envelope fraction of K2-19b, K2-19c, and (2) studying the resonant relation between K2-19b and K2-19c.

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.
