Neptune's Inner Moons and Rings Are Exposed Icy Body Interiors
M. Ryleigh Davis, Matthew Belyakov, Ian Wong +2
JWST spectroscopy of Neptune's inner moons (Larissa, Galatea, Proteus) and its rings shows no water ice but a distinctive 2.72 µm magnesium‑rich phyllosilicate band, indicating the…
Deuterated water and the formation of the satellites of Uranus
Michael E. Brown, Matthew Belyakov, Swaroop Chandra +5
The satellites of Uranus orbit in a low-eccentricity, equatorial plane that is tilted by 98 degrees relative to the solar system -- a geometry that mirrors Uranus's extreme axial t…
Nereid as a Regular Satellite of Neptune
Matthew Belyakov, M. Ryleigh Davis, Ian Wong +2
Nereid, Neptune's third largest moon, is considered to be a captured irregular satellite due to its highly eccentric orbit. However, among irregular satellites, Nereid is an outlie…
Formation and Trapping of CO2 from Cryogenic Irradiation of Carbonate
Ashma Pandya, Swaroop Chandra, Michael E. Brown
The detection of CO2 on the Jovian satellite Europa by Galileo NIMS and recent mapping of the leading side by JWST has revealed that it is most concentrated in geologically young t…
The Fate of Frozen Carbonated Water at Europa-like Conditions
Swaroop Chandra, William T. P. Denman, Michael E. Brown
We present the results of experiments probing the retention of CO2 in crystalline water ice, frozen sodium chloride (NaCl) brines, and flash-frozen carbonated water using diffuse r…
Deuterated water ice on the satellites of Saturn
Michael E. Brown, Samantha K. Trumbo, M. Ryleigh Davis +1
The deuterium to hydrogen ratio in water ice in a planetary body carries important information on the history of water processing and delivery in the protostellar nebula. For a gia…
