L 363-38 b: a planet newly discovered with ESPRESSO orbiting a nearby M dwarf star
Lia F. Sartori, Christophe Lovis, Jean-Baptiste Delisle +7
Context. Planets around stars in the solar neighbourhood will be prime targets for characterisation with upcoming large space- and ground-based facilities. Since large-scale exopla…
Analytical determination of orbital elements using Fourier analysis. II. Gaia astrometry and its combination with radial velocities
J. -B. Delisle, D. Ségransan
The ESA global astrometry space mission Gaia has been monitoring the position of a billion stars since 2014. The analysis of such a massive dataset is challenging in terms of the d…
A CHEOPS-enhanced view of the HD3167 system
V. Bourrier, A. Deline, A. Krenn +92
Much remains to be understood about the nature of exoplanets smaller than Neptune, most of which have been discovered in compact multi-planet systems. With its inner ultra-short pe…
Global dynamics and architecture of the Kepler-444 system
M. Stalport, E. C. Matthews, V. Bourrier +3
S-type planets, which orbit one component of multiple-star systems, place strong constraints on the planet formation and evolution models. A notable case study is Kepler-444, a tri…
Unbiasing the density of TTV-characterised sub-Neptunes: Update of the mass-radius relationship of 34 Kepler planets
A. Leleu, J. -B. Delisle, S. Udry +7
Transit Timing Variations (TTVs) can provide useful information on compact multi-planetary systems observed by transits, by putting constraints on the masses and eccentricities of…
Gaia DR3 astrometric orbit determination with Markov Chain Monte Carlo and Genetic Algorithms. Systems with stellar, substellar, and planetary mass companions
B. Holl, A. Sozzetti, J. Sahlmann +8
Astrometric discovery of sub-stellar mass companions orbiting stars is exceedingly hard due to the required sub-milliarcsecond precision, limiting the application of this technique…
