The CHEOPS view of HD 95338b: refined transit parameters, and a search for exomoons
Sz. Kálmán, A. E. Simon, A. Deline +90
Despite the ever-increasing number of known exoplanets, no uncontested detections have been made of their satellites, known as exomoons. The quest to find exomoons is at the forefr…
The KELT-7b atmospheric thermal-inversion conundrum revisited with CHEOPS, TESS, and additional data
Z. Garai, A. Krenn, P. E. Cubillos +84
Ultrahot Jupiters are predicted to show inverted temperature-pressure (T-P) profiles in the presence of optical absorbers such as TiO and VO. An inverted T-P profile of KELT-7b was…
Dark skies of the slightly eccentric WASP-18 b from its optical-to-infrared dayside emission
A. Deline, P. E. Cubillos, L. Carone +86
We performed a joint analysis of phase-curve observations of the ultra-hot Jupiter WASP-18 b from the visible to the mid-infrared, using data from CHEOPS, TESS and Spitzer. We aim…
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…
The PLATO field selection process. II. Characterization of LOPS2, the first long-pointing field
V. Nascimbeni, G. Piotto, J. Cabrera +26
PLAnetary Transits and Oscillations of stars (PLATO) is an ESA M-class mission to be launched by the end of 2026 to discover and characterize transiting planets around bright and n…
Transit-timing variations in the AU Mic system observed with CHEOPS
Ã. 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…
