Improving exoplanet mass characterisation with Bayesian model selection using the Learned Harmonic Mean Estimator
Ross S. Dobson, Vincent Van Eylen, Ioanna Manolopoulou +1
Radial velocity (RV) analyses require modelling choices (such as eccentricity treatment, noise model, velocity trends, and number of planets) that can significantly affect derived…
Constraining Small Planet Compositions for Future Missions
Larissa Palethorpe, Annelies Mortier, Jo Ann Egger +14
Accurate mass and radius measurements of small transiting exoplanets are essential for probing their compositions, formation histories, and potential habitability. We present a uni…
Determining the impact of post-main-sequence stellar evolution on the transiting giant planet population
Edward M. Bryant, Vincent Van Eylen
The post-main sequence evolution of stars is expected to impact the exoplanets residing on close-in orbits around them. Using photometric data from the TESS Full-Frame-Images we ha…
A transiting giant planet in orbit around a 0.2-solar-mass host star
Edward M. Bryant, Andrés Jordán, Joel D. Hartman +56
Planet formation models suggest that the formation of giant planets is significantly harder around low-mass stars, due to the scaling of protoplanetary disc masses with stellar mas…
HD 35843: A Sun-like star hosting a long period sub-Neptune and inner super-Earth
Katharine Hesse, Ismael Mireles, François Bouchy +52
We report the discovery and confirmation of two planets orbiting the metal-poor Sun-like star, HD 35843 (TOI 4189). HD 35843 c is a temperate sub-Neptune transiting planet with an…
