Phase-dependent chemistry of WASP-43 b revealed with a suite of one-, two-, and three-dimensional models
Robin Baeyens, Julianne I. Moses, Jasmina Blecic +17
Our goal is to investigate the chemistry of the hot Jupiter WASP-43 b in detail using theoretical models, considering the constraints of the James Webb Space Telescope MIRI phase c…
The Mid-Infrared Transmission Spectrum of the Temperate Sub-Neptune TOI-270 d
Måns Holmberg, Nikku Madhusudhan, Martin Binet +3
Observations of temperate sub-Neptunes with JWST have ushered in a new era for atmospheric characterization of small exoplanets. In particular, the MIRI instrument provides a uniqu…
The compositions of the HR 8799 planets reflect accretion of both solids and metal-enriched gas
Jerry W. Xuan, Jean-Baptiste Ruffio, Yayaati Chachan +24
With four giant planets (, $T_\rm{eff}\sim900-1200$ K) orbiting between 15-70 au, HR 8799 provides an unparalleled testbed for studying giant planet formatio…
New Constraints on DMS and DMDS in the Atmosphere of K2-18 b from JWST MIRI
Nikku Madhusudhan, Savvas Constantinou, Måns Holmberg +3
The sub-Neptune frontier has opened a new window into the rich diversity of planetary environments beyond the solar system. The possibility of hycean worlds, with planet-wide ocean…
A photochemical PHO network for hydrogen-dominated exoplanet atmospheres
Elspeth K. H. Lee, Shang-Min Tsai, Julianne I. Moses +3
Due to the detection of phosphine PH3 in the Solar System gas giants Jupiter and Saturn, PH3 has long been suggested to be detectable in exosolar substellar atmospheres too. Howeve…
Towards a self-consistent evaluation of gas dwarf scenarios for temperate sub-Neptunes
Frances E. Rigby, Lorenzo Pica-Ciamarra, Måns Holmberg +6
The recent JWST detections of carbon-bearing molecules in a habitable-zone sub-Neptune have opened a new era in the study of low-mass exoplanets. The sub-Neptune regime spans a wid…
Volatile-rich Sub-Neptunes as Hydrothermal Worlds: The Case of K2-18 b
Cindy N. Luu, Xinting Yu, Christopher R. Glein +8
Temperate exoplanets between the sizes of Earth and Neptune, known as "sub-Neptunes", have emerged as intriguing targets for astrobiology. It is unknown whether these planets resem…
Seasonal variation of Saturn's Lyman- brightness
P. Stephenson, T. T. Koskinen, Z. Brown +5
We examine Saturn's non-auroral (dayglow) emissions at Lyman- observed by the {Cassini/UVIS} instrument from 2004 until 2016, to constrain meridional and seasonal trends in the…
Sulphur dioxide in the mid-infrared transmission spectrum of WASP-39b
Diana Powell, Adina D. Feinstein, Elspeth K. H. Lee +70
The recent inference of sulphur dioxide (SO) in the atmosphere of the hot (1100 K), Saturn-mass exoplanet WASP-39b from near-infrared JWST observations suggests that phot…
Hydrogen sulfide and metal-enriched atmosphere for a Jupiter-mass exoplanet
Guangwei Fu, Luis Welbanks, Drake Deming +15
As the closest transiting hot Jupiter to Earth, HD 189733b has been the benchmark planet for atmospheric characterization. It has also been the anchor point for much of our theoret…
Probing Cold-to-Temperate Exoplanetary Atmospheres: The Role of Water Condensation on Surface Identification with JWST
Ziyu Huang, Xinting Yu, Shang-Min Tsai +5
Understanding the surface temperature and interior structure of cold-to-temperate sub-Neptunes is critical for assessing their habitability, yet direct observations are challenging…
Nightside clouds and disequilibrium chemistry on the hot Jupiter WASP-43b
Taylor J. Bell, Nicolas Crouzet, Patricio E. Cubillos +80
Hot Jupiters are among the best-studied exoplanets, but it is still poorly understood how their chemical composition and cloud properties vary with longitude. Theoretical models pr…
Carbon-bearing Molecules in a Possible Hycean Atmosphere
Nikku Madhusudhan, Subhajit Sarkar, Savvas Constantinou +3
The search for habitable environments and biomarkers in exoplanetary atmospheres is the holy grail of exoplanet science. The detection of atmospheric signatures of habitable Earth-…
Early Release Science of the Exoplanet WASP-39b with JWST NIRSpec G395H
Lili Alderson, Hannah R. Wakeford, Munazza K. Alam +89
Measuring the abundances of carbon and oxygen in exoplanet atmospheres is considered a crucial avenue for unlocking the formation and evolution of exoplanetary systems. Access to a…
Photochemically-produced SO in the atmosphere of WASP-39b
Shang-Min Tsai, Elspeth K. H. Lee, Diana Powell +82
Photochemistry is a fundamental process of planetary atmospheres that regulates the atmospheric composition and stability. However, no unambiguous photochemical products have been…
