Evolution and Observable Properties of Rocky Planet Atmospheres
Marie-Luise Steinmeyer, Lena Noack, Philipp Baumeister +9
This review summarizes current knowledge of rocky exoplanet atmospheres, covering their formation, escape processes, long‑term interaction with the surface and interior, and the ro…
A New Global Chemical Equilibrium Code: Refractory Element Signatures in Super-Earths and Sub-Neptunes
Simon Grimm, Marie-Luise Steinmeyer, Aaron Werlen +3
The atmospheres of super-Earths and sub-Neptunes can be strongly modified by chemical exchange with their molten interiors during long-lived magma ocean phases. Interpreting atmosp…
Coupled Thermal-Chemical Evolution Models of Sub-Neptunes Reveal Atmospheric Signatures of Their Formation Location
Marie-Luise Steinmeyer, Caroline Dorn, Aaron Werlen +1
The observed masses and radii of sub-Neptunes are typically explained by the gas dwarf and the water world scenarios. While their evolutionary history on a population level has bee…
Densities of small planets around the M dwarfs TOI-4336 A and TOI-4342 with ESPRESSO: Three sub-Neptunes, one super-Earth, and a Neptune-mass candidate
Léna Parc, Charles Cadieux, Nolan Grieves +27
We present the characterization of two planetary systems orbiting the M dwarfs TOI-4336 A (M3.5V) and TOI-4342 (M0V), each hosting two transiting planets previously validated with…
Fundamentals of interior modelling and challenges in the interpretation of observed rocky exoplanets
Philipp Baumeister, Francesca Miozzi, Claire Marie Guimond +7
Most our knowledge about rocky exoplanets is based on their measure of mass and radius. These two parameters are routinely measured and are used to categorise different populations…
