A window for water-hydrogen demixing on warm metal-rich sub-Neptunes
Caroline Piaulet-Ghorayeb, Daniel P. Thorngren, Eliza M. -R. Kempton +4
Sub-Neptunes represent the largest exoplanet demographic, yet their bulk compositions remain poorly understood. Recent studies suggested that only very cold planets, such as Uranus…
Constraining exoplanet interiors using observations of their atmospheres
Tim Lichtenberg, Oliver Shorttle, Johanna Teske +1
Astronomical surveys have identified numerous exoplanets with bulk compositions that are unlike the planets of the Solar System, including rocky super-Earths and gas-enveloped sub-…
Magma ocean interactions can explain JWST observations of the sub-Neptune TOI-270 d
Matthew C. Nixon, R. Sander Somers, Arjun B. Savel +9
Sub-Neptunes with substantial atmospheres may possess magma oceans in contact with the overlying gas, with chemical interactions between the atmosphere and magma playing an importa…
Limb Asymmetries on WASP-39b: A Multi-GCM Comparison of Chemistry, Clouds, and Hazes
Maria E. Steinrueck, Arjun B. Savel, Duncan A. Christie +27
With JWST, observing separate spectra of the morning and evening limbs of hot Jupiters has finally become a reality. The first such observation was reported for WASP-39b, where the…
Not All Sub-Neptune Exoplanets Have Magma Oceans
Bodie Breza, Matthew C. Nixon, Eliza M. -R. Kempton
The evolution and structure of sub-Neptunes may be strongly influenced by interactions between the outer gaseous envelope of the planet and a surface magma ocean. However, given th…
The JWST Rocky Worlds DDT Program reveals GJ 3929b to likely be a bare rock
Qiao Xue, Michael Zhang, Brandon P. Coy +14
We report first results from the JWST Rocky Worlds Director's Discretionary Time program. Two secondary eclipses of the terrestrial exoplanet GJ 3929b were recently observed using…
