Observation and Simulation of Mutual Approximations between Five Main Uranian Satellites
The Astronomical JournalMutual approximation is an emerging method for obtaining high-precision astrometric measurements of natural satellites and asteroids. We used the 80 cm YaoAn High Precision Telescope to observe mutual approximation events of the main Uranian satellites ...

Spectroscopic Links among Giant Planet Irregular Satellites and Trojans
The Planetary Science Journal, 2023 We collect near-infrared spectra (∼0.75–2.55 μ m) of four Jovian irregular satellites and visible spectra (∼0.32–1.00 μ m) of two Jovian irregular satellites, two Uranian irregular satellites, and four Neptune Trojans.

Strong Tidal Dissipation at Uranus?
The Planetary Science Journal, 2023 Geophysical estimates of paleo heat fluxes on the Uranian moons Miranda and Ariel are in the range of 25–75 mW m ^−2 . For a canonical Uranus dissipation factor Q = 18,000, expected equilibrium tidal heating rates for these satellites are less than 6 mW ...

Unraveling the Geologic History of Miranda’s Inverness Corona
The Planetary Science Journal, 2023 Miranda is the only icy body whose surface is known to contain the enigmatic features called corona—ovoid to trapezoidal areas of deformation. In this work, we seek to constrain potential formation mechanisms for Inverness Corona, the youngest known ...

Longitudinal Variation of H2O Ice Absorption on Miranda
The Planetary Science Journal, 2022 Many tidally locked icy satellites in the outer solar system show leading/trailing hemispherical asymmetries in the strength of near-infrared (NIR) H _2 O ice absorption bands, in which the absorption bands are stronger on the leading hemisphere. This is

Titania's Heat Fluxes Revealed by Messina Chasmata
The Planetary Science Journal, 2023 Messina Chasmata is a relatively young tectonic structure on Titania based on cross-cutting relationships, although an absolute age has not been estimated.

A CO2 Cycle on Ariel? Radiolytic Production and Migration to Low-latitude Cold Traps
The Planetary Science Journal, 2022 CO _2 ice is present on the trailing hemisphere of Ariel but is mostly absent from its leading hemisphere. The leading/trailing hemispherical asymmetry in the distribution of CO _2 ice is consistent with radiolytic production of CO _2 , formed by charged

Photometry of Irregular Satellites of Uranus and Neptune [PDF]
, 2004 We present BVR photometric colors of six Uranian and two Neptunian irregular satellites, collected using the Magellan Observatory (Las Campanas, Chile) and the Keck Observatory, (Manua Kea, Hawaii).

Are NH3 and CO2 Ice Present on Miranda?
The Planetary Science Journal, 2023 Published near-IR spectra of the four largest classical Uranian satellites display the presence of discrete deposits of CO _2 ice, along with subtle absorption features around 2.2 μ m.
