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…

PICASO 4.0: Clouds and Photochemistry in Climate Models of Brown Dwarfs and Exoplanets

James Mang, Natasha E. Batalha, Caroline V. Morley +8

We present a major update to the open-source atmospheric modeling package \texttt{PICASO}, designed for simulating the thermal structure and spectra of hydrogen-rich atmospheres of…

Accelerating Radiative Transfer for Planetary Atmospheres by Orders of Magnitude with a Transformer-Based Machine Learning Model

Isaac Malsky, Tiffany Kataria, Natasha E. Batalha +1

Radiative transfer calculations are essential for modeling planetary atmospheres. However, standard methods are computationally demanding and impose accuracy-speed trade-offs. High…

Surprise non-detection of Upsilon Andromedae b with MIRC-X and MYSTIC at the CHARA Array

Tyler Gardner, John D. Monnier, Stefan Kraus +11

Ground-based long baseline interferometry is a powerful tool for characterizing exoplanets which are too close to their host star to be imaged with single-dish telescopes. The CHAR…

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…
