Is the hot, dense sub-Neptune TOI-824b an exposed Neptune mantle? Spitzer detection of the hot day side and reanalysis of the interior composition
Pierre-Alexis Roy, Björn Benneke, Caroline Piaulet +10
The Kepler and TESS missions revealed a remarkable abundance of sub-Neptune exoplanets. Despite this abundance, our understanding of the nature and compositional diversity of sub-N…
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 G395H
Lili Alderson, Hannah R. Wakeford, Munazza K. Alam +89
Measuring the abundances of carbon and oxygen in exoplanet atmospheres is considered a crucial avenue for unlocking the formation and evolution of exoplanetary systems. Access to a…
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…
A strong H- opacity signal in the near-infrared emission spectrum of the ultra-hot Jupiter KELT-9b
Bob Jacobs, Jean-Michel Désert, Lorenzo Pino +11
We present the analysis of a spectroscopic secondary eclipse of the hottest transiting exoplanet detected to date, KELT-9b, obtained with the Wide Field Camera 3 aboard the Hubble…
Photochemically-produced SO in the atmosphere of WASP-39b
Shang-Min Tsai, Elspeth K. H. Lee, Diana Powell +82
Photochemistry is a fundamental process of planetary atmospheres that regulates the atmospheric composition and stability. However, no unambiguous photochemical products have been…
The Roasting Marshmallows Program with IGRINS on Gemini South I: Composition and Climate of the Ultra Hot Jupiter WASP-18 b
Matteo Brogi, Vanessa Emeka-Okafor, Michael R. Line +19
We present high-resolution dayside thermal emission observations of the exoplanet WASP-18b using IGRINS on Gemini South. We remove stellar and telluric signatures using standard al…
The Climate and Compositional Variation of the Highly Eccentric Planet HD 80606 b -- the rise and fall of carbon monoxide and elemental sulfur
Shang-Min Tsai, Maria Steinrueck, Vivien Parmentier +2
The gas giant HD 80606 b has a highly eccentric orbit (e 0.93). The variation due to the rapid shift of stellar irradiation provides a unique opportunity to probe the physic…
Identification of carbon dioxide in an exoplanet atmosphere
The JWST Transiting Exoplanet Community Early Release Science Team, Eva-Maria Ahrer, Lili Alderson +129
Carbon dioxide (CO2) is a key chemical species that is found in a wide range of planetary atmospheres. In the context of exoplanets, CO2 is an indicator of the metal enrichment (i.…
Spatially-resolving the terminator: Variation of Fe, temperature and winds in WASP-76 b across planetary limbs and orbital phase
Siddharth Gandhi, Aurora Kesseli, Ignas Snellen +5
Exoplanet atmospheres are inherently three-dimensional systems in which thermal/chemical variation and winds can strongly influence spectra. Recently, the ultra-hot Jupiter WASP-76…
Giant Planets from the Inside-Out
Tristan Guillot, Leigh N. Fletcher, Ravit Helled +3
Giant planets acquire gas, ices and rocks during the early formation stages of planetary systems and thus inform us on the formation process itself. Proceeding from inside out, exa…
A New Analysis of 8 Spitzer Phase Curves and Hot Jupiter Population Trends: Qatar-1b, Qatar-2b, WASP-52b, WASP-34b, and WASP-140b
Erin May, Kevin Stevenson, Jacob Bean +16
With over 30 phase curves observed during the warm Spitzer mission, the complete data set provides a wealth of information relating to trends and three-dimensional properties of ho…
Confirmation of Water Absorption in the Thermal Emission Spectrum of the Hot Jupiter WASP-77Ab with HST/WFC3
Megan Mansfield, Lindsey Wiser, Kevin B. Stevenson +11
Secondary eclipse observations of hot Jupiters can reveal both their compositions and thermal structures. Previous observations have shown a diversity of hot Jupiter eclipse spectr…
Carbon monoxide emission lines reveal an inverted atmosphere in the ultra hot Jupiter WASP-33 b consistent with an eastward hot spot
Lennart van Sluijs, Jayne L. Birkby, Joshua Lothringer +7
We report the first detection of CO emission at high spectral resolution in the day-side infrared thermal spectrum of an exoplanet. These emission lines, found in the atmosphere of…
