The Physical Nature of Regolith on Icy Moons
Cyril Mergny, Thomas Cornet, Alice Le Gall +8
Estimating surface properties such as porosity and grain sizes is key for planning lander missions and landing site selection on icy moons. However, spaceborne instruments do not m…
The Blinking Crystallinity of Europa: A Competition between Irradiation and Thermal Alteration
Cyril Mergny, Frédéric Schmidt, Felix Keil
The surface of Europa experiences a competition between thermally-induced crystallization and radiation-induced amorphization processes, leading to changes of its crystalline struc…
LunaIcy: Exploring Europa's Icy Surface Microstructure through Multiphysics Simulations
Cyril Mergny, Frédéric Schmidt
A multiphysics simulation model incorporating a sintering model coupled with the MultIHeaTS thermal solver was developed to study the evolution of icy moons' microstructure. The si…
MultIHeaTS: A Fast and Stable Thermal Solver for Multilayered Planetary Surfaces
Cyril Mergny, Frédéric Schmidt
A fully implicit scheme is proposed for solving the heat equation in 1D heterogeneous media, available as a computationally efficient open-source Python code. The algorithm uses fi…
