CHEOPS photometry from 2024 reveals a reversal in the transit-timing variations of AU Mic c
Z. Garai, Gy. M. Szabó, D. Gandolfi +90
We present new CHEOPS transit observations of AU Mic b and AU Mic c obtained between June and September 2024, extending the baseline of transit-timing measurements of this young pl…
A possible misaligned orbit for the young planet AU Mic c
H. Yu, Z. Garai, M. Cretignier +98
The AU Microscopii planetary system is only 24 Myr old, and its geometry may provide clues about the early dynamical history of planetary systems. Here, we present the first measur…
A joint effort to discover and characterize two resonant mini Neptunes around TOI-1803 with TESS, HARPS-N and CHEOPS
T. Zingales, L. Malavolta, L. Borsato +130
We present the discovery of two mini Neptunes near a 2:1 orbital resonance configuration orbiting the K0 star TOI-1803. We describe their orbital architecture in detail and suggest…
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…
Characterising TOI-732 b and c: New insights into the M-dwarf radius and density valley
A. Bonfanti, M. Brady, T. G. Wilson +88
TOI-732 is an M dwarf hosting two transiting planets that are located on the two opposite sides of the radius valley. By doubling the number of available space-based observations a…
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…
A new dynamical modeling of the WASP-47 system with CHEOPS observations
V. Nascimbeni, L. Borsato, T. Zingales +80
Among the hundreds of known hot Jupiters (HJs), only five have been found to have companions on short-period orbits. Within this rare class of multiple planetary systems, the archi…
A full transit of Lupi d and the search for an exomoon in its Hill sphere with CHEOPS
D. Ehrenreich, L. Delrez, B. Akinsanmi +90
The planetary system around the naked-eye star Lupi (HD 136352; TOI-2011) is composed of three exoplanets with masses of 4.7, 11.2, and 8.6 Earth masses. The TESS and CHEOPS…
Investigating the architecture and internal structure of the TOI-561 system planets with CHEOPS, HARPS-N and TESS
G. Lacedelli, T. G. Wilson, L. Malavolta +115
We present a precise characterization of the TOI-561 planetary system obtained by combining previously published data with TESS and CHEOPS photometry, and a new set of HARPS-N…
