A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067
R. Luque, H. P. Osborn, A. Leleu +149
Planets with radii between that of the Earth and Neptune (hereafter referred to as sub-Neptunes) are found in close-in orbits around more than half of all Sun-like stars. Yet, thei…
Exploring the Brown Dwarf Desert with Precision Radial Velocities and Gaia DR3 Astrometric Orbits
N. Unger, D. Ségransan, D. Barbato +4
Context. The observed scarcity of brown dwarfs in close orbits (within 10 au) around solar-type stars poses significant questions about the origins of these substellar companions.…
A review of planetary systems around HD 99492, HD 147379 and HD 190007 with HARPS-N
M. Stalport, M. Cretignier, S. Udry +26
The Rocky Planet Search (RPS) program is dedicated to a blind radial velocity (RV) search of planets around bright stars in the Northern hemisphere, using the high-resolution echel…
DREAM II. The spin-orbit angle distribution of close-in exoplanets under the lens of tides
M. Attia, V. Bourrier, J. -B. Delisle +1
The spin-orbit angle, or obliquity, is a powerful observational marker that allows us to access the dynamical history of exoplanetary systems. Here, we have examined the distributi…
A statistical model of stellar variability. I. FENRIR: a physics-based model of stellar activity, and its fast Gaussian process approximation
Nathan C. Hara, Jean-Baptiste Delisle
The detection of terrestrial planets by radial velocity and photometry is hindered by the presence of stellar signals. Those are often modeled as stationary Gaussian processes, who…
The CORALIE survey for southern extrasolar planets XIX. Brown dwarfs and stellar companions unveiled by radial velocity and astrometry
D. Barbato, D. Ségransan, S. Udry +17
A historical planet-search on a sample of 1647 nearby southern main sequence stars has been ongoing since 1998 with the CORALIE spectrograph at La Silla Observatory, with a backup…
