Benchmarking the ab initio hydrogen equations of state for the interior structure of Jupiter
S. Mazevet, A. Licari, F. Soubiran
As Juno is presently measuring Jupiter's gravitational moments to unprecedented accuracy, models for the interior structure of the planet are putted to the test. While equations of…
The Effects of Robin Boundary Condition on Thermal Convection in a Rotating Spherical Shell
Thibaut Clarté, Nathanaël Schaeffer, Stéphane Labrosse +1
Convection in a spherical shell is widely used to model fluid layers of planets and stars. The choice of thermal boundary conditions in such models is not always straightforward. T…
Voluminous silica precipitated from martian waters during late-stage aqueous alteration
L. Pan, J. Carter, C. Quantin-Nataf +6
Mars' transition from an early "warm and wet" to the "cold and dry" environment left fingerprints on the geological record of fluvial activity on Mars. The morphological and minera…
MUSE observations of comet 67P/Churyumov-Gerasimenko: A reference for future comet observations with MUSE
C. Opitom, A. Guilbert-Lepoutre, S. Besse +2
Observations of comet 67P/Churyumov-Gerasimenko were performed with MUSE at large heliocentric distances post-perihelion, between March 3 and 7, 2016. Those observations were part…
A multi-decadal view of the heat and mass budget of a volcano in unrest: La Soufrière de Guadeloupe (French West Indies)
David E. Jessop, Séverine Moune, Roberto Moretti +11
Particularly in the presence of a hydrothermal system, many volcanoes output large quantities of heat through the transport of water from deep within the edifice to the surface. Th…
Low thermal conductivity of iron-silicon alloys at Earth core conditions with implications for the geodynamo
Wen-Pin Hsieh, Alexander F. Goncharov, Stéphane Labrosse +5
Earth core is composed of iron (Fe) alloyed with light elements, e.g., silicon (Si). Its thermal conductivity critically affects Earth thermal structure, evolution, and dynamics, a…
Real-space formulation of the stress tensor for density functional theory: application to high temperature calculations
Abhiraj Sharma, Sebastien Hamel, Mandy Bethkenhagen +2
We present an accurate and efficient real-space formulation of the Hellmann-Feynman stress tensor for Kohn-Sham density functional theory (DFT). While applicable a…
Carbon ionization at Gbar pressures: an ab initio perspective on astrophysical high-density plasmas
Mandy Bethkenhagen, Bastian B. L. Witte, Maximilian Schörner +6
A realistic description of partially-ionized matter in extreme thermodynamic states is critical to model the interior and evolution of the multiplicity of high-density astrophysica…
Dynamo action in sliding plates of anisotropic electrical conductivity
Thierry Alboussiere, Kamel Drif, Franck Plunian
With materials of anisotropic electrical conductivity, it is possible to generate a dynamo with a simple velocity field, of the type precluded by Cowling's theorems with isotropic…
Axisymmetric dynamo action is possible with anisotropic conductivity
Franck Plunian, Thierry Alboussière
A milestone of dynamo theory is Cowling's theorem, known in its modern form as the impossibility for an axisymmetric velocity field to generate an axisymmetric magnetic field by dy…
Constraints on the composition and temperature of LLSVPs from seismic properties of lower mantle minerals
Kenny Vilella, Thomas Bodin, Charles-Edouard Boukaré +4
Here, we provide a reappraisal of potential LLSVPs compositions based on an improved mineralogical model including, for instance, the effects of alumina. We also systematically inv…
Interstellar comet 2I/Borisov as seen by MUSE: C, NH and red CN detections
Michele T. Bannister, Cyrielle Opitom, Alan Fitzsimmons +11
We report the clear detection of C and of abundant NH in the first prominently active interstellar comet, 2I/Borisov. We observed 2I on three nights in November 2019 at opt…
Magnesium Oxide at Extreme Temperatures and Pressures Studied with First-Principles Simulations
François Soubiran, Felipe González-Cataldo, Kevin P. Driver +2
We combine two first-principles computer simulation techniques, path integral Monte-Carlo and density functional theory molecular dynamics, to determine the equation of state of ma…
Path Integral Monte Carlo and Density Functional Molecular Dynamics Simulations of Warm, Dense MgSiO
Felipe González-Cataldo, François Soubiran, Henry Peterson +1
In order to provide a comprehensive theoretical description of MgSiO at extreme conditions, we combine results from path integral Monte Carlo (PIMC) and density functional mole…
