Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903
Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173
Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…

Detection of an Earth-sized exoplanet orbiting the nearby ultracool dwarf star SPECULOOS-3
Michaël Gillon, Peter P. Pedersen, Benjamin V. Rackham +81
Located at the bottom of the main sequence, ultracool dwarf stars are widespread in the solar neighbourhood. Nevertheless, their extremely low luminosity has left their planetary p…

A new generation of observatories is enabling detailed study of exoplanetary atmospheres and the diversity of alien climates, allowing us to seek evidence for extraterrestrial biol…
A super-Earth and a mini-Neptune near the 2:1 MMR straddling the radius valley around the nearby mid-M dwarf TOI-2096
F. J. Pozuelos, M. Timmermans, B. V. Rackham +72
Several planetary formation models have been proposed to explain the observed abundance and variety of compositions of super-Earths and mini-Neptunes. In this context, multitransit…
GJ 806 (TOI-4481): A bright nearby multi-planetary system with a transiting hot, low-density super-Earth
E. Palle, J. Orell-Miquel, M. Brady +63
One of the main scientific goals of the TESS mission is the discovery of transiting small planets around the closest and brightest stars in the sky. Here, using data from the CARME…
