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…
Two temperate super-Earths transiting a nearby late-type M dwarf
L. Delrez, C. A. Murray, F. J. Pozuelos +82
In the age of JWST, temperate terrestrial exoplanets transiting nearby late-type M dwarfs provide unique opportunities for characterising their atmospheres, as well as searching fo…
