The Uranian moon Ariel exhibits a diversity of geologically young landforms, with a surface composition rich in CO _2 ice. The origin of CO _2 and other species, however, remains uncertain. We report observations of Ariel’s leading and trailing hem

The Differential Speckle Survey Instrument (DSSI) was relocated to the Astrophysical Research Consortium 3.5 m telescope at Apache Point Observatory (APO) in early 2022. Here we present results from the first year of observations along with an update

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. The two innermost satellites, Miranda and Ariel, also possess su

Near-infrared spectra of Umbriel and the other classical Uranian moons exhibit 2.2 μ m absorption bands that could result from ammonia (NH _3 ) bearing species, possibly exposed in the geologically recent past. However, Umbriel has an ancient surfac

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. Thi

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 cha
