Characterizing planetary systems with SPIRou: Detection of a sub-Neptune in a 6-day period orbit around the M dwarf Gl 410

A. Carmona, X. Delfosse, M. Ould-Elhkim +42

The search for exoplanets around nearby M dwarfs represents a crucial milestone in the census of planetary systems in the vicinity of our Solar System. Since 2018 our team is carry…

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…

SWEET-Cat: A view on the planetary mass-radius relation

S. G. Sousa, V. Adibekyan, E. Delgado-Mena +9

SWEET-Cat (Stars With ExoplanETs Catalogue) was originally introduced in 2013, and since then, the number of confirmed exoplanets has increased significantly. A crucial step for a…

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…

New ephemerides and detection of transit-timing variations in the K2-138 system using high-precision CHEOPS photometry

H. G. Vivien, S. Hoyer, M. Deleuil +5

Multi-planet systems are a perfect laboratory for constraining planetary formation models. A few of these systems present planets that come very close to mean motion resonance, pot…
