Geomagnetic dipole stability and zonal flows controlled by mantle heat flux heterogeneities
Thomas Frasson, Natanaël Schaeffer, Henri-Claude Nataf +1
This work aims at acquiring a more complete understanding of how lateral heterogeneities of the CMB heat flux affect the geodynamo while other relevant parameters are pushed toward…
Dynamic regimes in planetary cores: τ-{\ell} diagrams
Henri-Claude Nataf, Nathanaël Schaeffer
Planetary cores are the seat of rich and complex fluid dynamics, in which the effects of rotation and magnetic field combine. The equilibria governing the strength of the magnetic…
Tidally synchronized solar dynamo: a rebuttal
Henri-Claude Nataf
The idea of a planetary origin for the solar cycle dates back to the nineteenth century. Despite unsurmounted problems, it is still advocated by some. Stefani, Giesecke, and Weier…
Acoustic spectra of a gas-filled rotating spheroid
Sylvie Su, David Cébron, Henri-Claude Nataf +4
The acoustic spectrum of a gas-filled resonating cavity can be used to indirectly probe its internal velocity field. This unconventional velocimetry method is particularly interest…
Turbulent geodynamo simulations: a leap towards Earth's core
Nathanaël Schaeffer, Dominique Jault, Henri-Claude Nataf +1
We present an attempt to reach realistic turbulent regime in direct numerical simulations of the geodynamo. We rely on a sequence of three convection-driven simulations in a rapidl…
Dynamic Domains of DTS: Simulations of a Spherical Magnetized Couette Flow
Elliot Kaplan, Henri-Claude Nataf, Nathanaël Schaeffer
The Derviche Tourneur Sodium experiment, a spherical Couette magnetohydrodynamics experiment with liquid sodium as the medium and a dipole magnetic field imposed from the inner sph…
