The similarity of multi-planet systems

J. F. Otegi, R. Helled, F. Bouchy

Previous studies using Kepler data suggest that planets orbiting the same star tend to have similar sizes. However, due to the faintness of the stars, only a few of the planets wer…

Fundamental physics with ESPRESSO: Precise limit on variations in the fine-structure constant towards the bright quasar HE 05154414

Michael T. Murphy, Paolo Molaro, Ana C. O. Leite +40

The strong intervening absorption system at redshift 1.15 towards the very bright quasar HE 05154414 is the most studied absorber for measuring possible cosmological variations…

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).…

Warm terrestrial planet with half the mass of Venus transiting a nearby star

Olivier D. S. Demangeon, M. R. Zapatero Osorio, Y. Alibert +42

The advent of a new generation of radial velocity instruments has allowed us to break the one Earth-mass barrier. We report a new milestone in this context with the detection of th…

Populating the brown dwarf and stellar boundary: Five stars with transiting companions near the hydrogen-burning mass limit

Nolan Grieves, François Bouchy, Monika Lendl +52

We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exopla…

TESS and HARPS reveal two sub-Neptunes around TOI 1062

J. F. Otegi, F. Bouchy, R. Helled +46

The Transiting Exoplanet Survey Satellite (\textit{TESS}) mission was designed to perform an all-sky search of planets around bright and nearby stars. Here we report the discovery…
