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…
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…
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…
An improved correction of radial-velocity systematic for the SOPHIE spectrograph
S. Grouffal, A. Santerne, N. C. Hara +4
High precision spectrographs might exhibit temporal variations of their reference velocity or nightly zero point (NZP). One way to monitor the NZP is to measure bright stars, which…
