Transmission spectra of all cloud models for WASP-107b compared with the JWST NIRCam observations (black points). Dotted lines show small-particle models dominated by Rayleigh scattering (0.1 µm Na2S, KCl, MgSiO3); dashed lines are over-clouded models with suppressed molecular features (1 µm Na2S and MgSiO3); dot-dashed lines are under-clouded models with large features (10 µm Na2S; 5, 10 µm KCl; 10 µm MgSiO3). Solid lines indicate the three best-fit models: 5 µm Na2S (blue), 1 µm KCl (green), and 5 µm MgSiO3 (red). -- astro-ph.EP

The Tale Of The 3 Planets: 3D Cloud Feedback Enhances The Spectral Diversity Of Warm Jupiters

by Keith CowingApril 30, 2026April 30, 2026

JWST has shown a large diversity in warm Jupiter spectra, despite only small variations in the planetary parameters. However, the main driver of this diversity remains unclear. We aim to […]

A diagram showing how data flows through the transformer architecture implemented here. Data padding and masking are left out for simplicity. The model does implement this functionality, but it is not necessary for our constant-length sequences. -- astro-ph.EP

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

by Keith CowingNovember 7, 2025November 7, 2025

Radiative transfer calculations are essential for modeling planetary atmospheres. However, standard methods are computationally demanding and impose accuracy-speed trade-offs. High computational costs force numerical simplifications in large models (e.g., General […]
