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…
