NGTS-33b: A Young Super-Jupiter Hosted by a Fast Rotating Massive Hot Star
Douglas R. Alves, James S. Jenkins, Jose I. Vines +22
In the last few decades planet search surveys have been focusing on solar type stars, and only recently the high-mass regimes. This is mostly due to challenges arising from the lac…
Characterisation of TOI-406 as showcase of the THIRSTEE program: A 2-planet system straddling the M-dwarf density gap
G. Lacedelli, E. Pallè, R. Luque +31
The exoplanet sub-Neptune population currently poses a conundrum, as to whether small-size planets are volatile-rich cores without an atmosphere, or rocky cores surrounded by a H-H…
From super-Earths to sub-Neptunes: Observational constraints and connections to theoretical models
Léna Parc, François Bouchy, Julia Venturini +2
We have updated the PlanetS catalog of transiting planets with precise and robust mass and radius measurements and use this catalog to explore mass-radius (M-R) diagrams. On the on…
Resonant sub-Neptunes are puffier
Adrien Leleu, Jean-Baptiste Delisle, Remo Burn +12
A systematic, population-level discrepancy exists between the densities of exoplanets whose masses have been measured with transit timing variations (TTVs) versus those measured wi…
NIRPS first light and early science: breaking the 1 m/s RV precision barrier at infrared wavelengths
Étienne Artigau, François Bouchy, René Doyon +111
The Near-InfraRed Planet Searcher or NIRPS is a precision radial velocity spectrograph developed through collaborative efforts among laboratories in Switzerland, Canada, Brazil, Fr…
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…
Discovery of two warm mini-Neptunes with contrasting densities orbiting the young K3V star TOI-815
Angelica Psaridi, Hugh Osborn, François Bouchy +130
We present the discovery and characterization of two warm mini-Neptunes transiting the K3V star TOI-815 in a K-M binary system. Analysis of the spectra and rotation period reveal i…
