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…
Debris Disks can Contaminate Mid-Infrared Exoplanet Spectra: Evidence for a Circumstellar Debris Disk around Exoplanet Host WASP-39
Laura Flagg, Alycia J. Weinberger, Taylor J. Bell +21
The signal from a transiting planet can be diluted by astrophysical contamination. In the case of circumstellar debris disks, this contamination could start in the mid-infrared and…
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…
The Variable Detection of Atmospheric Escape around the young, Hot Neptune AU Mic b
Keighley E. Rockcliffe, Elisabeth R. Newton, Allison Youngblood +5
Photoevaporation is a potential explanation for several features within exoplanet demographics. Atmospheric escape observed in young Neptune-sized exoplanets can provide insight in…
Probing reflection from aerosols with the near-infrared dayside spectrum of WASP-80b
Bob Jacobs, Jean-Michel Désert, Peter Gao +9
The presence of aerosols is intimately linked to the global energy budget and the composition of a planet's atmospheres. Their ability to reflect incoming light prevents energy fro…
Rocky planet or water world? Observability of low-density lava world atmospheres
Anjali A. A. Piette, Peter Gao, Kara Brugman +4
Super-Earths span a wide range of bulk densities, indicating a diversity in interior conditions beyond that seen in the solar system. In particular, an emerging population of low-d…
A reflective, metal-rich atmosphere for GJ 1214b from its JWST phase curve
Eliza M. -R. Kempton, Michael Zhang, Jacob L. Bean +30
There are no planets intermediate in size between Earth and Neptune in our Solar System, yet these objects are found around a substantial fraction of other stars. Population statis…
The Hazy and Metal-Rich Atmosphere of GJ 1214 b Constrained by Near and Mid-Infrared Transmission Spectroscopy
Peter Gao, Anjali A. A. Piette, Maria E. Steinrueck +12
The near-infrared transmission spectrum of the warm sub-Neptune exoplanet GJ 1214 b has been observed to be flat and featureless, implying a high metallicity atmosphere with abunda…
Stability and detectability of exomoons orbiting HIP 41378 f, a temperate Jovian planet with an anomalously low apparent density
Caleb K. Harada, Courtney D. Dressing, Munazza K. Alam +21
Moons orbiting exoplanets ("exomoons") may hold clues about planet formation, migration, and habitability. In this work, we investigate the plausibility of exomoons orbiting the te…
A First Look at the JWST MIRI/LRS Phase Curve of WASP-43b
Taylor J. Bell, Laura Kreidberg, Sarah Kendrew +7
We observed a full-orbit phase curve of the hot Jupiter WASP-43b with MIRI/LRS as part of the Transiting Exoplanet Community Early Release Science Program. Here we report prelimina…
The effect of interior heat flux on the atmospheric circulation of hot and ultra-hot Jupiters
Thaddeus D. Komacek, Peter Gao, Daniel P. Thorngren +2
Many hot and ultra-hot Jupiters have inflated radii, implying that their interiors retain significant entropy from formation. These hot interiors lead to an enhanced internal heat…
Early Release Science of the exoplanet WASP-39b with JWST NIRISS
Adina D. Feinstein, Michael Radica, Luis Welbanks +86
Transmission spectroscopy provides insight into the atmospheric properties and consequently the formation history, physics, and chemistry of transiting exoplanets. However, obtaini…
Early Release Science of the exoplanet WASP-39b with JWST NIRCam
Eva-Maria Ahrer, Kevin B. Stevenson, Megan Mansfield +96
Measuring the metallicity and carbon-to-oxygen (C/O) ratio in exoplanet atmospheres is a fundamental step towards constraining the dominant chemical processes at work and, if in eq…
Early Release Science of the exoplanet WASP-39b with JWST NIRSpec PRISM
Z. Rustamkulov, D. K. Sing, S. Mukherjee +91
Transmission spectroscopy of exoplanets has revealed signatures of water vapor, aerosols, and alkali metals in a few dozen exoplanet atmospheres. However, these previous inferences…
Into the UV: The Atmosphere of the Hot Jupiter HAT-P-41b Revealed
Nikole K. Lewis, Hannah R. Wakeford, Ryan J. MacDonald +19
For solar-system objects, ultraviolet spectroscopy has been critical in identifying sources for stratospheric heating and measuring the abundances of a variety of hydrocarbon and s…
The Need for Laboratory Measurements and Ab Initio Studies to Aid Understanding of Exoplanetary Atmospheres
Jonathan J. Fortney, Tyler D. Robinson, Shawn Domagal-Goldman +85
We are now on a clear trajectory for improvements in exoplanet observations that will revolutionize our ability to characterize their atmospheric structure, composition, and circul…
Life Beyond the Solar System: Remotely Detectable Biosignatures
Shawn Domagal-Goldman, Nancy Y. Kiang, Niki Parenteau +38
For the first time in human history, we will soon be able to apply the scientific method to the question "Are We Alone?" The rapid advance of exoplanet discovery, planetary systems…
