Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903

Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173

Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…

Chromaticity of stellar activity in radial velocities : Anti-correlated families of lines on the M dwarf EV Lac with SPIRou and SOPHIE

Pierre Larue, Xavier Delfosse, Andres Carmona +33

Context. In the search for exoplanets using radial velocities (RV), stellar activity has become one of the main limiting factors for detectability. Fortunately, activity-induced RV…

BEBOP VII. SOPHIE discovery of BEBOP-3b, a circumbinary giant planet on an eccentric orbit

Thomas A. Baycroft, Alexandre Santerne, Amaury H. M. J. Triaud +21

Planetary systems orbiting close binaries are valuable testing grounds for planet formation and migration models. More detections with good mass measurements are needed. We present…

BEBOP V. Homogeneous Stellar Analysis of Potential Circumbinary Planet Hosts

Alix V. Freckelton, Daniel Sebastian, Annelies Mortier +29

Planets orbiting binary systems are relatively unexplored compared to those around single stars. Detections of circumbinary planets and planetary systems offer a first detailed vie…

Planetary system LHS 1140 revisited with ESPRESSO and TESS

J. Lillo-Box, P. Figueira, A. Leleu +17

LHS 1140 is an M dwarf known to host two known transiting planets at orbital periods of 3.77 and 24.7 days. The external planet (LHS 1140 b) is a rocky super-Earth that is located…

Bias and robustness of eccentricity estimates from radial velocity data

N. C. Hara, G. Boué, J. Laskar +2

Eccentricity is a parameter of particular interest as it is an informative indicator of the past of planetary systems. It is however not always clear whether the eccentricity fitte…
