  • Title of programme: Refining parameters of grazing transiting exoplanets with CHEOPS and TESS
  • Abstract: Grazing transiting exoplanets still constitute only a tiny fraction of the known exoplanet population. However, confirming/investigating grazing transiting exoplanets is also important. In a grazing transit, the second and third contact points are missing, the transit profile is V-shaped, similar to that of an eclipsing binary. Consequently, the light-curve solution is degenerate. Fortunately, there is a solution: we need very high-quality multicolour photometric observations. Following this possibility, we propose to utilise the colour difference between TESS and CHEOPS in order to refine the parameters and to confirm the grazing nature of selected transiting exoplanets, namely TOI-3540 b and TOI-2193 b.

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.
