  • Title of programme: ANCILLARY SCIENCE - Recovering ephemeris
  • Abstract: There are a number (about 2 tens) of transiting planetst of interest for follow-up characterizing measurements (JWST, E-ELT), whose ephemeris must be recovered before going with large facilities, and this can be done by CHEOPS. It is proposed to monitor one transit per target; the observing window centered on the transit time predicted by the best available ephemeris, and lasting two times the uncertainty on T0 plus the transit duration. Target list and target priority shall be modified according to results from K2 and TESS campaigns.

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.
