Searching for Hot Water World Candidates with CHEOPS: Refining the radii and analysing the internal structures and atmospheric lifetimes of TOI-238 b and TOI-1685 b
J. A. Egger, D. Kubyshkina, Y. Alibert +85
Studying the composition of exoplanets is one of the most promising approaches to observationally constrain planet formation and evolution processes. However, this endeavour is com…
Transit-timing variations in the AU Mic system observed with CHEOPS
Á. Boldog, Gy. M. Szabó, L. Kriskovics +86
AU Mic is a very active M dwarf with an edge-on debris disk and two transiting sub-Neptunes with a possible third planetary companion. The two transiting planets exhibit significan…
Unveiling the internal structure and formation history of the three planets transiting HIP 29442 (TOI-469) with CHEOPS
J. A. Egger, H. P. Osborn, D. Kubyshkina +91
Multiplanetary systems spanning the radius valley are ideal testing grounds for exploring the proposed explanations for the observed bimodality in the radius distribution of close-…
Precise characterisation of HD 15337 with CHEOPS: a laboratory for planet formation and evolution
N. M. Rosário, O. D. S. Demangeon, S. C. C. Barros +90
We aim to constrain the internal structure and composition of HD 15337 b and c, two short-period planets situated on opposite sides of the radius valley, using new transit photomet…
Refined parameters of the HD 22946 planetary system and the true orbital period of planet d
Z. Garai, H. P. Osborn, D. Gandolfi +85
Multi-planet systems are important sources of information regarding the evolution of planets. However, the long-period planets in these systems often escape detection. HD 22946 is…
Examining the orbital decay targets KELT-9 b, KELT-16 b and WASP-4 b, and the transit-timing variations of HD 97658 b
J. -V. Harre, A. M. S. Smith, S. C. C. Barros +87
Tidal orbital decay is suspected to occur especially for hot Jupiters, with the only observationally confirmed case of this being WASP-12 b. By examining this effect, information o…
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…
Characterization of the HD 108236 system with CHEOPS and TESS. Confirmation of a fifth transiting planet
S. Hoyer, A. Bonfanti, A. Leleu +87
The HD108236 system was first announced with the detection of four small planets based on TESS data. Shortly after, the transit of an additional planet with a period of 29.54d was…
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…
Spi-OPS: Spitzer and CHEOPS confirm the near-polar orbit of MASCARA-1 b and reveal a hint of dayside reflection
M. J. Hooton, S. Hoyer, D. Kitzmann +82
The light curves of tidally locked hot Jupiters transiting fast-rotating, early-type stars are a rich source of information about both the planet and star, with full-phase coverage…
The changing face of AU Mic b: stellar spots, spin-orbit commensurability, and Transit Timing Variations as seen by CHEOPS and TESS
Gy. M. Szabó, D. Gandolfi, A. Brandeker +78
AU Mic is a young planetary system with a resolved debris disc showing signs of planet formation and two transiting warm Neptunes near mean-motion resonances. Here we analyse three…
The EChO science case
Giovanna Tinetti, Pierre Drossart, Paul Eccleston +347
The discovery of almost 2000 exoplanets has revealed an unexpectedly diverse planet population. Observations to date have shown that our Solar System is certainly not representativ…
