  • Title of programme: Axis 1 - YOUNGSTER: Monitoring of YOUNG STars for Exoplanet Recovery
  • Abstract: Young exoplanetary systems offer unique opportunities to study planetary systems which are still evolving to their mature distributions and compositions. However, the characterisation of young exoplanets is severely complicated by the stellar activity of their host stars. In order to precisely characterise young exoplanets, it is crucially important that we understand the behaviour of their host stars when measurements are taken. This programme represents a new CHEOPS filler program to photometrically monitor the stellar activity of several young exoplanet candidates from TESS while they are being actively followed up by the HARPS and NIRPS spectrographs to measure these planet candidates masses. These planet candidates are key targets to constrain early planet evolution, given their ages of <50Myr and position in the dynamic hot-Neptune desert/savanna.

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.
