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
MÃ¥ns 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, MÃ¥ns 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…
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…
