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.

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

Workshop on ICES reference points (WKREF1)
, 2022 The ICES Workshop on ICES reference points (WKREF1) was tasked to provide a thorough re-view of the ICES reference points system as a basis to re-evaluate the process for estimating, updating and communicating reference points in the context of the ICES ...

GEOLOGICAL MAPPING OF PLUTO AND CHARON USING NEW HORIZONS DATA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 Pluto and Charon exhibit strikingly different surface appearances, despite their similar densities and presumed bulk compositions. Systematic mapping has revealed that much of Pluto’s surface can be attributed to surface-atmosphere interactions and the ...

Crystallization Kinetics of Vitreous Magnesium Sulfate Hydrate and Implications for Europa’s Surface
The Planetary Science Journal, 2023 Brines consistent with that expected for Europa’s global subsurface ocean have been shown to form vitreous salt hydrates when frozen. We report experiments examining the crystallization kinetics of vitreous MgSO _4 hydrate in order to better understand ...

Closer look at the surface of ice [PDF]
Proceedings of the National Academy of Sciences, 2016 When hydrogen bonds are broken at an interface, water molecules are forced to adopt configurations that are not as energetically favorable as those deep within the bulk of the material. At the interface between ice and its vapor, this can result in the top layers of ice becoming disordered.

Astronomy & Astrophysics, 2006 Aims. We investigate the surface composition of Centaurs and Trans-Neptunian objects (TNOs) to get constraints on the formation and the evolution of this population. Methods. We report visible and near-infrared spectroscopic observations of the Plutino 55638 (2002 VE 5 ) obtained at VLT-ESO.

Molecule-specific diffusion and desorption of interstellar ices on carbonaceous dust
Astronomy & AstrophysicsInterstellar ices form on dust grains in the coldest regions of molecular clouds and preserve key volatile reservoirs that could be incorporated into protoplanetary disks during star and planet formation.
