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.

Scaling of convection in high-Pressure ice layers of large icy moons and implications for habitability

open access: yesIcarus (New York, N.Y. 1962), 2021
The existence of a high pressure ice layer between the silicate core and the liquid ocean in large icy moons and ocean worlds is usually seen as a barrier to habitability, preventing the compounds needed for life to flow into the ocean.

Multi-Layer Hydrostatic Equilibrium of Planets and Synchronous Moons: Theory and Application to Ceres and to Solar System Moons [PDF]

open access: yes, 2014
The hydrostatic equilibrium of multi-layer bodies lacks a satisfactory theoretical treatment despite its wide range of applicability. Here we show that by using the exact analytical potential of homogeneous ellipsoids we can obtain recursive analytical ...

The thermal emission of Saturn's icy moons. Effects of topography and regolith properties

open access: yesAstronomy & Astrophysics, 2021
Context. The effects of space weathering and other alteration processes on the upper surface of Saturn’s icy moons are yet to be explored. Aims. We present a thermophysical model parametrised by way of regolith properties such as porosity, grain size ...

Observation of nuclear quantum effects and hydrogen bond symmetrisation in high pressure ice

open access: yesNature Communications, 2018
Hydrogen atoms in water ices, under pressures at which they might exist in ocean exoplanets and icy moons, exhibit dynamics that are still poorly understood. Here, 1H-NMR experiments approaching the Mbar range shed light on the symmetrisation of hydrogen

Analysis of Temporal and Structural Characteristics of Jovian Radio Emissions for Passive Radar Sounding of Jupiter’s Icy Moons

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2021
Recent studies have proposed that Jovian decametric radiation (DAM) can be effectively exploited for probing the subsurface of Jupiter’s icy moons by using passive radio sounding.

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 ...

Reactivity of Cyanide at Water-Ice Interfaces: Implications for the Search for Organics on Icy Worlds

open access: yesFrontiers in Astronomy and Space Sciences, 2020
Icy moons in our solar system are targets of interest to search for signs of life and habitability beyond Earth. They are the astrobiological aim for several developing space missions (JUICE, Europa Clipper, and Europa Lander). A further understanding of

Consequences of large impacts on Enceladus' core shape [PDF]

open access: yes, 2015
International audienceThe intense activity on Enceladus suggests a differentiated interior consisting of a rocky core, an internal ocean and an icy mantle.
