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 gra…

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…

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…
