A Stellar-Type Dependence in the Rocky and Volatile Composition of Small Exoplanets
Ji Wang, Caroline Dorn, Komal Bali
We investigate the rocky and volatile composition of small exoplanets by modeling the population-level distribution of densities using a mixture framework that links interior struc…
Atmospheric diversity of sub-Neptunes from formation with rock, water, and soot
Caroline Dorn, Aaron Werlen, Sean Jordan
Recent JWST detections of CH4 and CO2 in sub-Neptune atmospheres point to a link between atmospheric composition and the nature of planetary building blocks - rock, water, or refra…
The Role of Formation Location in Shaping Sulfur-, Nitrogen-, and Carbon-Bearing Species in Super-Earth and Sub-Neptune Atmospheres
Aaron Werlen, Remo Burn, Caroline Dorn +2
Atmospheric compositions of sub-Neptunes and super-Earths are often interpreted as tracers of formation location relative to volatile ice lines. However, prolonged magma oceans can…
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…
The Effects of Non-ideal Mixing in Planetary Magma Oceans and Atmospheres
Aaron Werlen, Edward D. Young, Hilke E. Schlichting +2
Sub-Neptunes with hydrogen-rich envelopes are expected to sustain long-lived magma oceans that continuously exchange volatiles with their overlying atmospheres. Capturing these int…
Oxygen left behind: Atmospheric Enrichment due to Fractionation in Sub-Neptunes using BOREAS
Marilina Valatsou, Caroline Dorn, Pierlou Marty +1
The evolution of exoplanetary atmospheres is strongly influenced by atmospheric escape, particularly for close-in planets. Fractionation during atmospheric loss can preferentially…
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…
