Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Key Targets of Opportunity on Gas and Ice Giants and their satellites
Ricardo Hueso, Leigh N. Fletcher, Damya Souami +15
The Extremely Large Telescope (ELT) will transform our knowledge of the outer planets and their satellite systems; however the visibility of unique targets of opportunity with high…
Improved H2-He and H2-H2 Collision-Induced Absorption Models and Application to Outer-Planet Atmospheres
Glenn S. Orton, Magnus Gustafsson, Leigh N. Fletcher +2
Using state-of-the-art ab initio interaction-induced dipole and potential-energy surfaces for hydrogen-helium (H2-He) pairs, we compute the rototranslational collision-induced abso…
The Atmosphere of Titan in Late Northern Summer from JWST and Keck Observations
Conor A. Nixon, Bruno Bézard, Thomas Cornet +42
Saturn's moon Titan undergoes a long annual cycle of 29.45 Earth years. Titan's northern winter and spring were investigated in detail by the Cassini-Huygens spacecraft (2004-2017)…
Clouds and Hazes in GJ 1214b's Metal-Rich Atmosphere
Isaac Malsky, Emily Rauscher, Kevin Stevenson +10
The sub-Neptune GJ 1214b has an infamously flat transmission spectrum, likely due to thick aerosols in its atmosphere. A recent JWST MIRI spectroscopic phase curve of GJ 1214 b add…
Internal Heat and Energy Imbalance of Uranus
Xinyue Wang, Liming Li, Michael Roman +13
With its extreme axial tilt, radiant energy budget and internal heat of Uranus remain among the most intriguing mysteries of our Solar System. Here, we present the global radiant e…
The Thermal Structure and Composition of Jupiter's Great Red Spot From JWST/MIRI
Jake Harkett, Leigh N. Fletcher, Oliver R. T. King +15
Jupiter's Great Red Spot (GRS) was mapped by the James Webb Space Telescope (JWST)/Mid-Infrared Instrument (4.9-27.9 micron) in July and August 2022. These observations took place…
