The metal-poor atmosphere of a Neptune/Sub-Neptune planet progenitor
Saugata Barat, Jean-Michel Désert, Allona Vazan +12
Young transiting exoplanets offer a unique opportunity to characterize the atmospheres of fresh and evolving products of planet formation. We present the transmission spectrum of V…
Constraining Background N2 Inventories on Directly Imaged Terrestrial Exoplanets to Rule Out O2 False Positives
Sawyer Hall, Joshua Krissansen-Totton, Tyler Robinson +2
Direct imaging spectroscopy with future space-based telescopes will constrain terrestrial planet atmospheric composition and potentially detect biosignature gases. One promising in…
Outgassing Composition of the Murchison Meteorite: Implications for Volatile Depletion of Planetesimals and Interior-atmosphere Connections for Terrestrial Exoplanets
Maggie A. Thompson, Myriam Telus, Graham Harper Edwards +5
Outgassing is a central process during the formation and evolution of terrestrial planets and their atmospheres both within and beyond the solar system. Although terrestrial planet…
A roadmap for the atmospheric characterization of terrestrial exoplanets with JWST
TRAPPIST-1 JWST Community Initiative, :, Julien de Wit +80
Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominen…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems III: Aperture Masking Interferometric Observations of the star HIP 65426 at 3.8 um
Shrishmoy Ray, Steph Sallum, Sasha Hinkley +121
We present aperture masking interferometry (AMI) observations of the star HIP 65426 at as a part of the JWST Direct Imaging Early Release Science (ERS) program obtai…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems IV: NIRISS Aperture Masking Interferometry Performance and Lessons Learned
Steph Sallum, Shrishmoy Ray, Jens Kammerer +120
We present a performance analysis for the aperture masking interferometry (AMI) mode on board the James Webb Space Telescope Near Infrared Imager and Slitless Spectrograph (JWST/NI…
Clouds and Clarity: Revisiting Atmospheric Feature Trends in Neptune-size Exoplanets
Jonathan Brande, Ian J. M. Crossfield, Laura Kreidberg +12
Over the last decade, precise exoplanet transmission spectroscopy has revealed the atmospheres of dozens of exoplanets, driven largely by observatories like the Hubble Space Telesc…
Water absorption in the transmission spectrum of the water-world candidate GJ9827d
Pierre-Alexis Roy, Björn Benneke, Caroline Piaulet +16
Recent work on the characterization of small exoplanets has allowed us to accumulate growing evidence that the sub-Neptunes with radii greater than often host H…
Atmospheric Retrieval of L Dwarfs: Benchmarking Results and Characterizing the Young Planetary Mass Companion HD 106906 b in the Near-Infrared
Arthur D. Adams, Michael R. Meyer, Alex R. Howe +7
We present model constraints on the atmospheric structure of HD 106906 b, a planetary-mass companion orbiting at a ~700 AU projected separation around a 15 Myr-old stellar binary,…
Methane Throughout the Atmosphere of the Warm Exoplanet WASP-80b
Taylor J. Bell, Luis Welbanks, Everett Schlawin +12
The abundances of major carbon and oxygen bearing gases in the atmospheres of giant exoplanets provide insights into atmospheric chemistry and planet formation processes. Thermoche…
ELemental abundances of Planets and brown dwarfs Imaged around Stars (ELPIS): I. Potential Metal Enrichment of the Exoplanet AF Lep b and a Novel Retrieval Approach for Cloudy Self-luminous Atmospheres
Zhoujian Zhang, Paul Mollière, Keith Hawkins +10
AF Lep A+b is a remarkable planetary system hosting a gas-giant planet that has the lowest dynamical mass among directly imaged exoplanets. We present an in-depth analysis of the a…
ExoGemS High-Resolution Transmission Spectroscopy of WASP-76b with GRACES
Emily K. Deibert, Ernst J. W. de Mooij, Ray Jayawardhana +9
We present high-resolution transmission spectroscopy of WASP-76b with GRACES/Gemini North obtained as part of the ExoGemS survey. With a broad spectral range of 400-1050 nm and a r…
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…
A broadband thermal emission spectrum of the ultra-hot Jupiter WASP-18b
Louis-Philippe Coulombe, Björn Benneke, Ryan Challener +73
Close-in giant exoplanets with temperatures greater than 2,000 K (''ultra-hot Jupiters'') have been the subject of extensive efforts to determine their atmospheric properties using…
