Volatile depletion in rocky planets as a chemical fingerprint of hybrid accretion
Haiyang S. Wang, Anders Johansen, Ziyan Xu +7
Volatile depletion in rocky planets relative to their host stars is commonplace in both the Solar System and exoplanetary systems, yet the connections between planet formation and…
Evolution and Observable Properties of Rocky Planet Atmospheres
Marie-Luise Steinmeyer, Lena Noack, Philipp Baumeister +9
The atmospheric composition of rocky exoplanets offers an important tool for constraining the properties of the interior of this type of planet, beyond what is possible from measur…
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…
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…
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…
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…
Vapor equilibrium models of accreting rocky planets demonstrate direct core growth by pebble accretion
Marie-Luise Steinmeyer, Anders Johansen
The gaseous envelope of an accreting rocky planet becomes hot enough to sublimate silicates and other refractory minerals. For this work, we studied the effect of the resulting env…
Sublimation of refractory minerals in the gas envelopes of accreting rocky planets
Marie-Luise Steinmeyer, Peter Woitke, Anders Johansen
Protoplanets growing within the protoplanetary disk by pebble accretion acquire hydrostatic gas envelopes. Due to accretion heating, the temperature in these envelopes can become h…
