Probing Exoplanetary Chemistry with Ariel: Scientific Priorities and Observational Strategies
Olivia Venot, Yamila Miguel, Robin Baeyens +30
Over the past two decades, increasingly precise observations have revealed that exoplanet atmospheres are chemically diverse and often far from equilibrium, with processes such as…
Can the Long-Term Impact of Stellar M-Dwarf Flares Alter the Spectral Features of a Giant Gaseous Exoplanet?
Amy Louca, Shang-Min Tsai, Yamila Miguel
In this work, we model the long-term impact of recurrent stellar flares on the atmospheres of metal-rich gaseous exoplanets. Using synthetic flare spectra from a fiducial flare mod…
A parameterised approach to disequilibrium retrievals in the JWST era: Application to NIRCam observations of HD 189733b
Jake Taylor, Shang-Min Tsai, Vivien Parmentier +2
Atmospheric retrievals are a widely used technique for inferring the physical and chemical properties of exoplanetary atmospheres from observed spectra. A common simplifying assump…
Benchmarking Two Chemical Networks used in General Circulation Models of Hot Jupiters
D. A. Christie, M. Zamyatina, E. Hébrard +7
Chemical kinetics is becoming an increasingly vital component of hot Jupiter general circulation models (GCMs). Here we simulate the hot Jupiter WASP-96b using two chemical network…
Super-Solar Metallicity and Tentative Evidence for Photochemistry on WASP-96b from JWST and Ground-Based VLT Transmission Spectroscopy
Michael Radica, Jake Taylor, Yoav Rotman +13
With its expanded wavelength coverage and increased precision compared to previous space-based observatories, JWST provides the opportunity to revisit benchmark planets and view th…
BOWIE-ALIGN: Exploring degeneracies in the muted transmission spectrum of the aligned hot Jupiter NGTS-2b with NIRSpec/G395H
Charlotte Fairman, Hannah R. Wakeford, Alastair B. Claringbold +15
We present the first atmospheric observation and characterisation of the aligned, 1468 K hot Jupiter, NGTS-2b, with one JWST NIRSpec/G395H transit. These observations complete the…
JWST-TST DREAMS: The Nightside Emission and Chemistry of WASP-17b
Jacob Lustig-Yaeger, Kristin S. Sotzen, Kevin B. Stevenson +24
Theoretical studies have suggested using planetary infrared excess (PIE) to detect and characterize the thermal emission of transiting and non-transiting exoplanets, however the PI…
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…
Statistical trends in JWST transiting exoplanet atmospheres
Guangwei Fu, Kevin B. Stevenson, David K. Sing +13
Our brains are hardwired for pattern recognition as correlations are useful for predicting and understanding nature. As more exoplanet atmospheres are being characterized with JWST…
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…
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…
The Featherweight Giant: Unraveling the Atmosphere of a 17 Myr Planet with JWST
Pa Chia Thao, Andrew W. Mann, Adina D. Feinstein +29
The characterization of young planets (< 300 Myr) is pivotal for understanding planet formation and evolution. We present the 3-5m transmission spectrum of the 17 Myr, Jupiter-s…
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…
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…
