TESS phase curve of ultra-hot Jupiter WASP-189 b

J. A. Patel, D. Kitzmann, A. Brandeker +4

The thermal structures of highly irradiated ultra-hot Jupiters can deviate substantially from those of cooler hot Jupiters. For planets orbiting rapidly rotating, and consequently…

Characterisation of the TOI-421 planetary system using CHEOPS, TESS, and archival radial velocity data

A. F. Krenn, D. Kubyshkina, L. Fossati +88

The TOI-421 planetary system contains two sub-Neptune-type planets and is a prime target to study the formation and evolution of planets and their atmospheres. The inner planet is…

CHEOPS observations of KELT-20 b/MASCARA-2 b: An aligned orbit and signs of variability from a reflective dayside

V. Singh, G. Scandariato, A. M. S. Smith +87

Occultations are windows of opportunity to indirectly peek into the dayside atmosphere of exoplanets. High-precision transit events provide information on the spin-orbit alignment…

The geometric albedo of the hot Jupiter HD 189733b measured with CHEOPS

A. F. Krenn, M. Lendl, J. A. Patel +84

Context. Measurements of the occultation of an exoplanet at visible wavelengths allow us to determine the reflective properties of a planetary atmosphere. The observed occultation…

55 Cancri e's occultation captured with CHEOPS

B. -O. Demory, S. Sulis, E. Meier Valdes +73

Past occultation and phase-curve observations of the ultra-short period super-Earth 55 Cnc e obtained at visible and infrared wavelengths have been challenging to reconcile with a…

CHEOPS geometric albedo of the hot Jupiter HD 209458b

A. Brandeker, K. Heng, M. Lendl +74

We report the detection of the secondary eclipse of the hot Jupiter HD 209458b in optical/visible light using the CHEOPS space telescope. Our measurement of 20.4 +/- 3.3 ppm transl…
