Architecture of planetary systems with and without outer giant planets I. Inner planet detections around HD 23079, HD 196067, and HD 86226

J. -B. Delisle, J. P. Faria, D. Ségransan +22

Understanding the link between outer giant planets (OGPs) and inner light planets (ILPs) is key to understanding planetary system formation and architecture. The correlation betwee…

CORALIE radial-velocity search for companions around evolved stars (CASCADES) IV: New planetary systems around HD 87816, HD 94890, and HD 102888 and an update on HD 121056

E. Fontanet, S. Udry, D. Ségransan +25

With around 200 detections of exoplanets around giant stars to date, our knowledge of the population of exoplanets orbiting evolved hosts more massive than the Sun remains limited.…

In-depth characterization of the Kepler-10 three-planet system with HARPS-N radial velocities and Kepler transit timing variations

A. S. Bonomo, L. Borsato, V. M. Rajpaul +25

The old G3V star Kepler-10 is known to host two transiting planets, the ultra-short-period super-Earth Kepler-10b ( d; ) and the long-period s…

Discovery of a cold giant planet and mass measurement of a hot super-Earth in the multi-planetary system WASP-132

N. Grieves, F. Bouchy, D. J. Armstrong +25

Hot Jupiters generally do not have nearby planet companions, as they may have cleared out other planets during their inward migration from more distant orbits. This gives evidence…

Radial velocity homogeneous analysis of M dwarfs observed with HARPS I. Exoplanet detection and candidates

L. Mignon X. Delfosse, X. Bonfils, N. Meunier +11

The census of planets around M dwarfs in the solar neighbourhood meets two challenges: detecting the best targets for the future characterisation of planets with ELTs, and studying…

Revisiting the multi-planetary system of the nearby star HD 20794: Confirmation of a low-mass planet in the habitable zone of a nearby G-dwarf

N. Nari, X. Dumusque, N. C. Hara +44

Close-by Earth analogs and super-Earths are of primary importance because they will be preferential targets for the next generation of direct imaging instruments. Bright and close-…
