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…
A low-mass sub-Neptune planet transiting the bright active star HD 73344
S. Sulis, I. J. M. Crossfield, A. Santerne +33
Context. Planets with radii of between 2-4 RE closely orbiting solar-type stars are of significant importance for studying the transition from rocky to giant planets. Aims. Our goa…
Water content trends in K2-138 and other low-mass multiplanetary systems
Lorena Acuña, Theo Lopez, Thierry Morel +5
Super-Earths and sub-Neptunes have been found simultaneously in multiplanetary systems, suggesting that they are appropriate to study composition and formation within the same envi…
HD207897 b: A dense sub-Neptune transiting a nearby and bright K-type star
N. Heidari, I. Boisse, J. Orell-Mique +90
We present the discovery and characterization of a transiting sub-Neptune orbiting with a 16.20 day period around a nearby (28 pc) and bright(V=8.37) K0V star HD207897 (TOI-1611).…
TOI-1296b and TOI-1298b observed with TESS and SOPHIE: Two hot Saturn-mass exoplanets with different densities around metal-rich stars
C. Moutou, J. M. Almenara, G. Hébrard +40
We present the discovery of two new transiting extrasolar planet candidates identified as TOI-1296.01 and TOI-1298.01 by the Transiting Exoplanet Survey Satellite (TESS). The plane…
The SOPHIE search for northern extrasolar planets. XVIII: Six new cold Jupiters, including one of the most eccentric exoplanet orbits
O. D. S. Demangeon, S. Dalal, G. Hébrard +28
Context. Due to their low transit probability, the long-period planets are, as a population, only partially probed by transit surveys. Radial velocity surveys thus have a key role…
