Detection of propadiene (CH $_{2}$ CCH $_{2}$ ), propene (C $_{3}$ H $_{6}$ ) and non-detection of propane (C $_{3}$ H $_{8}$ ) in Jupiter's northern polar stratosphere

James A. Sinclair, Thomas K. Greathouse, Rohini S. Giles +8

We report the first detection of stratospheric propadiene (CH $_{2}$ CCH $_{2}$ ) and propene (C $_{3}$ H $_{6}$ ) at Jupiter's mid-to-high northern latitudes using IRTF-TEXES measurements recorde…

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 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…
