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…
A fading radius valley towards M-dwarfs, a persistent density valley across stellar types
Julia Venturini, María Paula Ronco, Octavio M. Guilera +3
The radius valley separating super-Earths from mini-Neptunes is a fundamental benchmark for theories of planet formation and evolution. Observations show that the location of the r…
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…
A radius valley between migrated steam worlds and evaporated rocky cores
Remo Burn, Christoph Mordasini, Lokesh Mishra +4
The radius valley (or gap) in the observed distribution of exoplanet radii, which separates smaller super-Earths from larger sub-Neptunes, is a key feature that theoretical models…
