The Days Drag On on WASP-121 b: Interpreting its NIRISS Spectroscopic Phase Curve with General Circulation Models

Robert C. Frazier, Emily Rauscher, Jared Splinter +18

Ultra-hot Jupiters present extreme atmospheric phenomena not found in the Solar System. These planets' daysides experience strong temperature inversions, molecular species (includi…

Limb Asymmetries on WASP-39b: A Multi-GCM Comparison of Chemistry, Clouds, and Hazes

Maria E. Steinrueck, Arjun B. Savel, Duncan A. Christie +27

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…

First Results from WINERED: Detection of Emission Lines from Neutral Iron and a Combined Set of Trace Species on the Dayside of WASP-189 b

Lennart van Sluijs, Emily Rauscher, Eliza M. -R. Kempton +9

Ground and space-based observations have revealed that Ultra Hot Jupiters (UHJs,~) typically have inverted thermal profiles, while cooler hot Jupiters…

Assessing robustness and bias in 1D retrievals of 3D Global Circulation Models at high spectral resolution: a WASP-76 b simulation case study in emission

Lennart van Sluijs, Hayley Beltz, Isaac Malsky +4

High-resolution spectroscopy (HRS) of exoplanet atmospheres has successfully detected many chemical species and is quickly moving toward detailed characterization of the chemical a…

A Panchromatic Characterization of the Evening and Morning Atmosphere of WASP-107 b: Composition and Cloud Variations, and Insight into the Effect of Stellar Contamination

Matthew M. Murphy, Thomas G. Beatty, Everett Schlawin +16

Limb-resolved transmission spectroscopy has the potential to transform our understanding of exoplanetary atmospheres. By separately measuring the transmission spectra of the evenin…

An Analysis of Spitzer Phase Curves for WASP-121b and WASP-77Ab

Brian Davenport, Thomas Kennedy, E. M. May +6

We present analyses of Spitzer InfraRed Array Camera (IRAC) 3.6 m and 4.5 m phase curve observations of hot Jupiters WASP-77Ab and WASP-121b. For WASP-121b, we find amplitu…
