  • Title of programme: Understanding stellar activity patterns by coupling absolute photometry and intense RV monitoring
  • Abstract: Nowadays, stellar activity constitutes the main obstacle to the detection of planets with sub-meter per second radial velocity (RV) amplitudes. In the near future, the PLATO mission will survey with high precision the photometric variations of bright stars in specific areas of the sky. The combination of those observations with the most precise spectrographs will certainly be of upmost interest to alleviate stellar activity effects, and provide mass measurements below the meter per second level needed to reach PLATOs science goals. CHEOPS represents a unique opportunity to take a step ahead in prevision of PLATO, and valuably support extensive RV surveys. The goal of this program is to combine parallel RV and CHEOPS photometric monitorings on a moderately active star, to unveil the nature of the activity patterns in both datasets.

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.
