  • Title of programme: Measuring Albedos for Different Hot JUpiters
  • Abstract: Hot Jupiters offer exceptional opportunities for atmospheric study, predominantly carried out with NIR/MIR spectroscopy. However, our scientific understanding their cloud properties remains limited and has been shown to affect both transmission and emission spectra significantly. Photometric observations in the optical are necessary to provide better constraints on the reflective properties of the atmosphere, improving our understanding of clouds and hazes. We propose observing three hot Jupiters--TOI 1518 b, KELT-7 b, and HD 202772 Ab. These planets orbit bright stars (G ~ 8), making them ideal CHEOPS targets. Their similar characteristics allow exploration of how varying temperatures influence atmospheric properties, complementing existing geometric albedo data. This effort aims to complement the sample of hot Jupiters with measured geometric albedos, furthering our understanding of atmospheric dynamics across these systems and ultimately improving interpretation of their composition and evolution.

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.
