Features in the visible spectra of the Enceladus particle plume and E ring: Potential evidence of organic materials and/or missing sub-micron particles
M. M. Hedman, S. M. MacKenzie
Visible spectra of the Enceladus particle plume and E ring contain evidence for a change in spectral slope around 0.5 micron. This feature can be seen in data obtained by both the…
Tracing the source of carbon oxides on the large moons of Uranus
Richard J. Cartwright, Sasha Cryan, Rosario Brunetto +15
The Uranian moons Ariel, Umbriel, Titania, and Oberon are enriched in CO2 mixed with CO, but the origin(s) of these carbon oxides, be they primarily native or radiolytic, remains u…
The Uranus System from Occultation Observations (1977-2006): Rings, Pole Direction, Gravity Field, and Masses of Cressida, Cordelia, and Ophelia
Richard G. French, Matthew M. Hedman, Philip D. Nicholson +2
From 31 Earth-based and three Voyager 2 occultations spanning 1977--2006, we determine the orbital elements of the nine main Uranian rings with typical RMS residuals of 0.2 -- 0.4…
The composition of Saturn's rings
Kelly E. Miller, Gianrico Filacchione, Jeffrey Cuzzi +12
The origin and evolution of Saturn's rings is critical to understanding the Saturnian system as a whole. Here, we discuss the physical and chemical composition of the rings, as a f…
Saturn's Atmosphere in Northern Summer Revealed by JWST/MIRI
Leigh N. Fletcher, Oliver R. T. King, Jake Harkett +8
Saturn's northern summertime hemisphere was mapped by JWST/MIRI (4.9-27.9 m) in November 2022, tracing the seasonal evolution of temperatures, aerosols, and chemical species in…
Ring Seismology of the Ice Giants Uranus and Neptune
Joseph A. A'Hearn, Matthew M. Hedman, Christopher R. Mankovich +2
We assess the prospect of using ring seismology to probe the interiors of the ice giants Uranus and Neptune. We do this by calculating normal mode spectra for different interior mo…
