Catastrophic disruption of asteroid 2023 CX1 and implications for planetary defense
Auriane Egal, Denis Vida, François Colas +94
Mitigation of the threat from airbursting asteroids requires an understanding of the potential risk they pose for the ground. How asteroids release their kinetic energy in the atmo…
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…
Data availability and requirements relevant for the Ariel space mission and other exoplanet atmosphere applications
Katy L. Chubb, Séverine Robert, Clara Sousa-Silva +52
The goal of this white paper is to provide a snapshot of the data availability and data needs primarily for the Ariel space mission, but also for related atmospheric studies of exo…
Gravity-Induced Ice Compaction and Subsurface Porosity on Icy Moons
Cyril Mergny, Frédéric Schmidt
Our understanding of the surface porosity of icy moons and its evolution with depth remains limited, including the precise scale at which ice compaction occurs under self-weight pr…
Circumpolar ocean stability on Mars 3 Gy ago
Schmidt F., Way M. J., Costard F. +3
What was the nature of the Late Hesperian climate? Warm and wet or cold and dry? Formulated this way the question leads to an apparent paradox since both options seem implausible.…
