  • Abstract: We have conducted an extensive search for non-transiting exoplanets in the TESS data via subtle photometric effects – primarily in the form of atmospheric modulation due to the orbiting exoplanet. We searched the 140,000 highest precision TESS light curves in the southern ecliptic hemisphere. We find 27 new short-period, giant exoplanet candidates, which are currently being monitored for radial velocity variations with HARPS. Of these two are ideal candidates to be followed up with CHEOPS, which will provide a high precision phase curve at a wavelength bluer than TESS to disentangle reflection and thermal emission. The candidates have extremely short periods of 0.88 and 0.74 days. The host stars are bright (g=11.2 and 11.5), and well-isolated from other bright sources. If successful, these would be the FIRST non-transiting exoplanets discovered by phase curves from the TESS/CHEOPS missions.

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.
