Surface charging of thick porous water ice layers relevant for ion sputtering experiments [PDF]

open access: yes, 2016
We use a laboratory facility to study the sputtering properties of centimeter-thick porous water ice subjected to the bombardment of ions and electrons to better understand the formation of exospheres of the icy moons of Jupiter.

Prospects for Cryovolcanic Activity on Cold Ocean Planets

open access: yesThe Astrophysical Journal, 2023
We have estimated total internal heating rates and depths to possible subsurface oceans for 17 planets that may be cold ocean planets, low-mass exoplanets with equilibrium surface temperatures and/or densities that are consistent with icy surfaces and a ...

Possibility for albedo estimation of exomoons: Why should we care about M dwarfs? [PDF]

open access: yes, 2016
Occultation light curves of exomoons may give information on their albedo and hence indicate the presence of ice cover on the surface. Icy moons might have subsurface oceans thus these may potentially be habitable.

Sieved mass and shape data from simulated fluvial transport of icy clasts in the Titan Tumbler

open access: yesData in Brief, 2022
Data in this article are related to the research article “Rapid rounding of icy clasts during simulated fluvial transport in the Titan Tumbler”. Whereas that research focused on low-temperature ice abrasion in the context of Saturn's moon Titan, the full

The Diverse Solar Phase Curves of Distant Icy Bodies. II. The Cause of the Opposition Surges and Their Correlations [PDF]

open access: yes, 2008
We collect well-measured opposition surge properties for many icy bodies orbiting the Sun (mostly from our own observations) plus for many icy moons, resulting in a data base of surface and orbital properties for 52 icy bodies.

Measurements of thermal properties of icy Mars regolith analogs [PDF]

open access: yes, 2012
In a series of laboratory experiments, we measure thermal diffusivity, thermal conductivity, and heat capacity of icy regolith created by vapor deposition of water below its triple point and in a low pressure atmosphere.

Models of dust around Europa and Ganymede [PDF]

open access: yes, 2012
We use numerical models, supported by our laboratory data, to predict the dust densities of ejecta outflux at any altitude within the Hill spheres of Europa and Ganymede.

Jupiter Science Enabled by ESA’s Jupiter Icy Moons Explorer

open access: yesSpace Science Reviews, 2023
AbstractESA’s Jupiter Icy Moons Explorer (JUICE) will provide a detailed investigation of the Jovian system in the 2030s, combining a suite of state-of-the-art instruments with an orbital tour tailored to maximise observing opportunities. We review the Jupiter science enabled by the JUICE mission, building on the legacy of discoveries from the Galileo,

Biological methane production under putative Enceladus-like conditions

open access: yesNature Communications, 2018
Many methanogenic archaea use H2 and CO2 to produce methane. Here, Taubner et al. show that Methanothermococcus okinawensis produces methane under conditions extrapolated for Saturn’s icy moon, Enceladus, and estimate that serpentinization may produce ...
