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…
Surrogate-Accelerated Bayesian Inversion for Exoplanet Interior Characterization
Tijn De Wringer, Caroline Dorn, Emily O. Garvin +1
Characterizing the interior structure of exoplanets is an inverse problem often solved using Bayesian inference, but this approach is hampered by the high computational cost of pla…
Sub-Neptunes Are Drier Than They Seem: Rethinking the Origins of Water-Rich Worlds
Aaron Werlen, Caroline Dorn, Remo Burn +3
Recent claims of biosignature gases in sub-Neptune atmospheres have renewed interest in water-rich sub-Neptunes with surface oceans, often referred to as Hycean planets. These plan…
