A Comprehensive Analysis Spitzer 4.5 m Phase Curve of Hot Jupiters
Lisa Dang, Taylor J. Bell, Ying +19
Although exoplanetary science was not initially projected to be a substantial part of the Spitzer mission, its exoplanet observations set the stage for current and future surveys w…
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…
Phase-resolving the absorption signatures of water and carbon monoxide in the atmosphere of the ultra-hot Jupiter WASP-121b with GEMINI-S/IGRINS
Joost P. Wardenier, Vivien Parmentier, Michael R. Line +12
Ultra-hot Jupiters are among the best targets for atmospheric characterization at high spectral resolution. Resolving their transmission spectra as a function of orbital phase offe…
Hydrogen sulfide and metal-enriched atmosphere for a Jupiter-mass exoplanet
Guangwei Fu, Luis Welbanks, Drake Deming +15
As the closest transiting hot Jupiter to Earth, HD 189733b has been the benchmark planet for atmospheric characterization. It has also been the anchor point for much of our theoret…
Multiple Clues for Dayside Aerosols and Temperature Gradients in WASP-69 b from a Panchromatic JWST Emission Spectrum
Everett Schlawin, Sagnick Mukherjee, Kazumasa Ohno +16
WASP-69 b is a hot, inflated, Saturn-mass planet 0.26 Mjup with a zero-albedo equilibrium temperature of 963 K. Here, we report the JWST 2 to 12 um emission spectrum of the planet…
Sulfur Dioxide and Other Molecular Species in the Atmosphere of the Sub-Neptune GJ 3470 b
Thomas G. Beatty, Luis Welbanks, Everett Schlawin +13
We report observations of the atmospheric transmission spectrum of the sub-Neptune exoplanet GJ 3470 b taken using the Near-Infrared Camera (NIRCam) on JWST. Combined with two arch…
Evidence for Morning-to-Evening Limb Asymmetry on the Cool Low-Density Exoplanet WASP-107b
Matthew M. Murphy, Thomas G. Beatty, Everett Schlawin +8
The atmospheric properties of hot exoplanets are expected to be different between the morning and the evening limb due to global atmospheric circulation. Ground-based observations…
A High Internal Heat Flux and Large Core in a Warm Neptune Exoplanet
Luis Welbanks, Taylor J. Bell, Thomas G. Beatty +16
Interactions between exoplanetary atmospheres and internal properties have long been hypothesized to be drivers of the inflation mechanisms of gaseous planets and apparent atmosphe…
High-precision atmospheric characterization of a Y dwarf with JWST NIRSpec G395H spectroscopy: isotopologue, C/O ratio, metallicity, and the abundances of six molecular species
Ben W. P. Lew, Thomas Roellig, Natasha E. Batalha +19
The launch of the James Webb Space Telescope (JWST) marks a pivotal moment for precise atmospheric characterization of Y dwarfs, the coldest brown dwarf spectral type. In this stud…
High-Precision Atmospheric Constraints for a Cool T Dwarf from JWST Spectroscopy
Callie E. Hood, Sagnick Mukherjee, Jonathan J. Fortney +12
We present observations of the T8 dwarf 2MASS 0415-0935 with JWST's NIRSpec spectrograph using the G395H grating ( 2.87 - 5.14 m). We perform the first atmospheric retriev…
