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…
CHEOPS observations confirm nodal precession in the WASP-33 system
A. M. S. Smith, Sz. Csizmadia, V. Van Grootel +86
Aims: We aim to observe the transits and occultations of WASP-33b, which orbits a rapidly-rotating Scuti pulsator, with the goal of measuring the orbital obliquity via the grav…
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…
In-situ observations of resident space objects with the CHEOPS space telescope
Nicolas Billot, Stephan Hellmich, Willy Benz +80
The CHaracterising ExOPlanet Satellite (CHEOPS) is a partnership between the European Space Agency and Switzerland with important contributions by 10 additional ESA member States.…
A close outer companion to the ultra-hot Jupiter TOI-2109 b?
J. -V. Harre, A. M. S. Smith, S. C. C. Barros +86
Hot Jupiters with close-by planetary companions are rare, with only a handful of them having been discovered so far. This could be due to their suggested dynamical histories, leadi…
Architecture of TOI-561 planetary system
G. Piotto, T. Zingales, L. Borsato +89
We present new observations from CHEOPS and TESS to clarify the architecture of the planetary system hosted by the old Galactic thick disk star TOI-561. Our global analysis, which…
The CHEOPS view on the climate of WASP-3 b
G. Scandariato, L. Carone, P. E. Cubillos +83
Hot Jupiters are giant planets subject to intense stellar radiation. The physical and chemical properties of their atmosphere makes them the most amenable targets for the atmospher…
The K2-24 planetary system revisited by CHEOPS
V. Nascimbeni, L. Borsato, P. Leonardi +82
K2-24 is a planetary system composed of two transiting low-density Neptunians locked in an almost perfect 2:1 resonance and showing large TTVs, i.e., an excellent laboratory to sea…
TOI-757 b: an eccentric transiting mini-Neptune on a 17.5-d orbit
A. Alqasim, N. Grieves, N. M. Rosário +129
We report the spectroscopic confirmation and fundamental properties of TOI-757 b, a mini-Neptune on a 17.5-day orbit transiting a bright star ( mag) discovered by the TESS…
Discovery of two warm mini-Neptunes with contrasting densities orbiting the young K3V star TOI-815
Angelica Psaridi, Hugh Osborn, François Bouchy +130
We present the discovery and characterization of two warm mini-Neptunes transiting the K3V star TOI-815 in a K-M binary system. Analysis of the spectra and rotation period reveal i…
