The star HIP 41378 potentially misaligned with its cohort of long-period planets
S. Grouffal, A. Santerne, V. Bourrier +29
The obliquity between the stellar spin axis and the planetary orbit, detected via the Rossiter-McLaughlin (RM) effect, is a tracer of the formation history of planetary systems. Wh…
EBLM XV -- Revised dynamical masses for the circumbinary planet host Kepler-16 AB, using the SOPHIE spectrograph
D. Sebastian, I. Boisse, A. Santerne +14
Eclipsing binaries are perfect laboratories to measure precise, accurate and model-independent stellar radii and stellar masses, so long as both components are spectroscopically re…
KOBE-1: The first planetary system from the KOBE survey. Two planets likely residing in the sub-Neptune mass regime around a late K-dwarf
O. Balsalobre-Ruza, J. Lillo-Box, A. M. Silva +35
K-dwarf stars are promising targets in the exploration of potentially habitable planets. Their properties, falling between G and M dwarfs, provide an optimal trade-off between the…
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…
TIC 172900988: A Transiting Circumbinary Planet Detected in One Sector of TESS Data
Veselin B. Kostov, Brian P. Powell, Jerome A. Orosz +86
We report the first discovery of a transiting circumbinary planet detected from a single sector of TESS data. During Sector 21, the planet TIC 172900988b transited the primary star…
WASP-39b: a highly inflated Saturn-mass planet orbiting a late G-type star
F. Faedi, S. C. C. Barros, D. R. Anderson +30
We present the discovery of WASP-39b, a highly inflated transiting Saturn-mass planet orbiting a late G-type dwarf star with a period of \,d, Transit Epoch T…
