The coupled impacts of atmospheric dynamics and cloud microphysics on hot Jupiter atmospheres. I. An application to WASP-43b
Emeline F. Fromont, Thaddeus D. Komacek, Peter Gao +9
Understanding the influence of cloud-circulation feedback on planetary climates is crucial to interpreting solar system and extrasolar planet observations. Hot Jupiter phase curve…
JWST MEP - A World Under Spotty Starlight: Detection of CO2 and H2O in the Hot Saturn WASP-52b with JWST NIRSpec G395H
JWST GO 3969 Team, Yanbo Pan, Ryan J. MacDonald +21
Exoplanets orbiting active stars offer distinct challenges for atmospheric characterization with the JWST. Among such worlds, the hot Saturn WASP-52b (Teq 1300 K) orbits an…
Wet Removal and Cloud Enhancement: The Microphysics of Cloud-Haze Interactions on Sub-Neptunes
Vighnesh Nagpal, Maria Steinrueck, Diana Powell +3
Aerosols are a near-ubiquitous feature of sub-Neptune atmospheres, yet their microphysical nature remains poorly understood. Both condensate clouds and photochemical hazes have bee…
Three dimensional temporal evolution of photochemical haze in exoplanet atmospheres I. Description and test application to HD 189733b
Elspeth K. H. Lee, Maria E. Steinrueck, Kazumasa Ohno +2
The formation and global spatial distribution of photochemically produced haze particles remain a key process in exoplanet atmospheres for understanding their observed properties.…
Photochemical Production of CS2 in Temperate-to-Warm Gas Giant Exoplanet Atmospheres
Jeehyun Yang, Vighnesh Nagpal, Michael Zhang +16
Sulfur chemistry has emerged as an important probe of exoplanet atmospheres in the JWST era, although observational constraints have thus far been largely limited to SO2 and H2S in…
Magnesium Silicate Clouds in the Atmosphere of HD 209458b from a Rule-Based Tree-Structured Data Reduction
Katy L. Chubb, David Grant, Hannah R. Wakeford +14
HD 209458b is the canonical hot Jupiter: the first to have its atmosphere measured and the first to hint at the role of aerosols in exoplanet atmospheres through the muting of Na a…
Cloudy With a Chance of Meatballs
Wolf Cukier, Dominic Samra, Vighnesh Nagpal +3
Speculative fiction has long served an inspiration for genuine scientific inquiry. One notable work that has almost acted in this manner is the the seminal comedic speculative fict…
Limb Asymmetries on WASP-39b: A Multi-GCM Comparison of Chemistry, Clouds, and Hazes
Maria E. Steinrueck, Arjun B. Savel, Duncan A. Christie +28
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…
Mapping the SO2 Shoreline in Gas Giant Exoplanets
Ian J. M. Crossfield, Eva-Maria Ahrer, Jonathan Brande +8
JWST has revealed sulfur chemistry in giant exoplanet atmospheres, where molecules such as SO2 trace photochemistry, metallicity, and formation and migration. To ascertain the cond…
Volcanic Satellites Tidally Venting Na, K, SO2 in Optical & Infrared Light
Apurva V. Oza, Andrea Gebek, Moritz Meyer zu Westram +19
Recent infrared spectroscopy from the James Webb Space Telescope (JWST) has spurred analyses of common volcanic gases such as carbon dioxide (CO2), sulfur dioxide (SO2), alongside…
BOWIE-ALIGN: Sub-stellar metallicity and carbon depletion in the aligned TrES-4b with JWST NIRSpec transmission spectroscopy
Annabella Meech, Alastair B. Claringbold, Eva-Maria Ahrer +19
The formation and migration history of a planet is expected to be imprinted in its atmosphere, in particular its carbon-to-oxygen (C/O) ratio and metallicity. The BOWIE-ALIGN progr…
BOWIE-ALIGN: JWST reveals hints of planetesimal accretion and complex sulphur chemistry in the atmosphere of the misaligned hot Jupiter WASP-15b
James Kirk, Eva-Maria Ahrer, Alastair B. Claringbold +23
We present a transmission spectrum of the misaligned hot Jupiter WASP-15b from 2.8-5.2 microns observed with JWST's NIRSpec/G395H grating. Our high signal to noise data, which has…
A Benchmark JWST Near-Infrared Spectrum for the Exoplanet WASP-39b
A. L. Carter, E. M. May, N. Espinoza +77
Observing exoplanets through transmission spectroscopy supplies detailed information on their atmospheric composition, physics, and chemistry. Prior to JWST, these observations wer…
Inhomogeneous terminators on the exoplanet WASP-39 b
Néstor Espinoza, Maria E. Steinrueck, James Kirk +40
Transmission spectroscopy has been a workhorse technique over the past two decades to constrain the physical and chemical properties of exoplanet atmospheres. One of its classical…
BOWIE-ALIGN: How formation and migration histories of giant planets impact atmospheric compositions
Anna B. T. Penzlin, Richard A. Booth, James Kirk +15
Hot Jupiters present a unique opportunity for measuring how planet formation history shapes present-day atmospheric composition. However, due to the myriad pathways influencing com…
BOWIE-ALIGN: A JWST comparative survey of aligned vs misaligned hot Jupiters to test the dependence of atmospheric composition on migration history
James Kirk, Eva-Maria Ahrer, Anna B. T. Penzlin +19
A primary objective of exoplanet atmosphere characterisation is to learn about planet formation and evolution, however, this is challenged by degeneracies. To determine whether dif…
