  • Title of programme: Confirming the Transit Timing Variations of a Neptune-Sized Inner Companion to a Hot Jupiter
  • Abstract: The presence of inner companions to Hot Jupiters reveals a rarely-treaded path of Hot Jupiter formation, one lacking its customary violence. Though intrinsically rare, such systems provide valuable opportunities to directly constrain migrational pathways and understand the multi-faceted origins of Hot Jupiters. TOI-5143 presents one such opportunity, hosting a confirmed Hot Jupiter TOI-5143.01 and a statistically-validated inner Neptune TOI-5143.02. TOI-5143.01 is one of the shortest-period Hot Jupiters to host an interior companion, second only to WASP-47. Preliminary ground-based photometric observations suggest that TOI-5143.02 exhibits tentative transit timing variations (TTVs). This program will use CHEOPS to confirm the TTV signals of TOI-5143.02. The TTV observations will be used with existing radial velocity data of the system to precisely constrain the mass and dynamical history of the system.

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.
