Improved characterization of the TOI-2141 system: a dense sub-Neptune with non-transiting inner and outer companions

R. Luque, K. W. F. Lam, J. Cabrera +87

We aim to refine the fundamental parameters of the TOI-2141 planetary system, which includes a transiting sub-Neptune orbiting a Sun-like star in a relatively long orbit of 18.26 d…

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…

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…

Characterisation of the Warm-Jupiter TOI-1130 system with CHEOPS and photo-dynamical approach

L. Borsato, D. Degen, A. Leleu +93

Among the thousands of exoplanets discovered to date, approximately a few hundred gas giants on short-period orbits are classified as "lonely" and only a few are in a multi-planet…

HIP 41378 observed by CHEOPS: Where is planet d?

S. Sulis, L. Borsato, S. Grouffal +84

HIP 41378 d is a long-period planet that has only been observed to transit twice, three years apart, with K2. According to stability considerations and a partial detection of the R…

Investigating the visible phase-curve variability of 55 Cnc e

E. A. Meier Valdés, B. M. Morris, B. -O. Demory +87

55 Cnc e is an ultra-short period super-Earth transiting a Sun-like star. Previous observations in the optical range detected a time-variable flux modulation that is phased with th…
