Dynamics of Y Dwarf Atmospheres
C. Akın, E. K. H. Lee, L. Gkouvelis +1
The global circulation regime of the coolest brown dwarfs, the Y dwarfs, remains largely unexplored. We investigate the interplay between convection, rotation, and cloud thermal fe…
The Albedo Problem and Cloud Cover on Hot Jupiters
Kevin Heng, Billy Edwards, Nicolas B. Cowan
Observations of transiting hot Jupiters have revealed a mismatch between the values of the Bond versus geometric albedos. In the planetary science literature, the ratio of these qu…
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…
The SPACE Program. I. The featureless spectrum of HD 86226 c challenges sub-Neptune atmosphere trends
K. Angelique Kahle, Jasmina Blecic, Reza Ashtari +26
Sub-Neptune exoplanets are the most abundant type of planet known today. As they do not have a Solar System counterpart, many open questions exist about their composition and forma…
