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…
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…
Atmospheric C/O Ratios of Sub-Neptunes with Magma Oceans: Homemade rather than Inherited
Aaron Werlen, Caroline Dorn, Hilke E. Schlichting +2
Recently, the James Webb Space Telescope has enabled detailed spectroscopic characterization of sub-Neptune atmospheres. With detections of carbon- and oxygen-bearing species such…
Water-rich sub-Neptunes and rocky super Earths around different Stars: Radii shaped by Volatile Partitioning, Formation, and Evolution
Remo Burn, Komal Bali, Caroline Dorn +2
The nature of sub-Neptunes remains unknown due to degeneracies in interior structure solutions. However, a statistical set of small planets with measured masses and radii can be us…
Impact of oxygen fugacity on atmospheric structure and emission spectra of ultra hot rocky exoplanets
Fabian L. Seidler, Paolo A. Sossi, Simon L. Grimm
Atmospheres above lava-ocean planets (LOPs) hold clues as to the properties of their interiors, owing to the expectation that the two reservoirs are in chemical equilibrium. Here w…
