A radius valley between migrated steam worlds and evaporated rocky cores
We provide a hybrid theoretical explanation of the radius gap and cliff caused by both planet formation (orbital migration) as well as evolution (atmospheric escape).
The Nominal Ranges of Rocky Planet Masses, Radii, Surface Gravities, and Bulk Densities
Here we present the open-source ExoPlex mass–radius–composition solver.
A pair of Sub-Neptunes transiting the bright K-dwarf TOI-1064 characterised with CHEOPS
We report the discovery and characterisation of a pair of sub-Neptunes transiting the bright K-dwarf TOI-1064.
Warm terrestrial planet with half the mass of Venus transiting a nearby star
The advent of a new generation of radial velocity instruments has allowed us to break the one Earth-mass barrier. We report a new milestone in this context with the detection of the lowest-mass planet measured so far using radial velocities: L 98-59 b, a rocky planet with half the mass of Venus.
Transit detection of the long-period volatile-rich super-Earth \(\nu^2\) Lupi d with CHEOPS
We report the detection of a long period exoplanet orbiting the naked-eye, Sun-like star \(\nu^2\) Lupi using data from the Characterising Exoplanets Satellite (CHEOPS).
A sub-Neptune and a non-transiting Neptune-mass companion unveiled by ESPRESSO around the bright late-F dwarf HD 5278 (TOI-130)
We exploit the extreme radial velocity (RV) precision of the ultra-stable echelle spectrograph ESPRESSO on the VLT to unveil the physical properties of the transiting sub-Neptune TOI-130 b.
Six transiting planets and a chain of Laplace resonances in TOI-178
We report the discovery and characterization of a planetary system in which five of the six planets are in Laplace resonance.
K2-111 an old system with two planets in near-resonance
This paper reports on the detailed characterisation of the K2-111 planetary system. Aside of K2-111 b, we announce the existence of a second sinusoidal signal in the radial velocity data, caused by a non-transiting planet, K2-111 c.
Refining the transit timing and photometric analysis of TRAPPIST-1: Masses, radii, densities, dynamics, and ephemerides
We have collected transit times of the system over four years. We find that all seven planets densities may be described with a single rocky mass-radius relation which is depleted in iron relative to Earth.
TOI-824 b: A New Planet on the Lower Edge of the Hot Neptune Desert
We report the detection of a transiting hot Neptune exoplanet orbiting TOI-824, a nearby K4V star, using data from the Transiting Exoplanet Survey Satellite (TESS).
The Nature of the Radius Valley: Hints from Formation and Evolution Models
The goal of this work is to provide insights into the existence of the Radius Valley from, first, a pure formation point of view, and second, a combined formation-evolution model. We run global planet formation simulations including the evolution of dust by coagulation, drift and fragmentation; and the evolution of the gaseous disc by viscous accretion and photoevaporation.
TESS reveals a short-period sub-Neptune sibling (HD 86226 c) to a known long-period giant planet
We present the detection and mass measurement of a small, short period transiting planet around the bright (V= 7.9), solar-type star HD 86226, previously known to host a long-period giant planet
A super-Earth and a sub-Neptune orbiting the bright, quiet M3 dwarf TOI-1266
We report the discovery and characterisation of a super-Earth and a sub-Neptune-sized planet transiting the bright (K=8.8), quiet and nearby (37pc) M3V dwarf TOI-1266.
The impact of exoplanets’ measured parameters on the inferred internal structure
We aim to study several aspects that affect internal characterization of super-Earths and sub-Neptunes.
Planetary mass-radius relations across the galaxy
We show that there is a persistent statistical difference in the expected mass-radius relations of solid planets between the different galactic stellar populations.
