Semi-convection in rotating spherical shells: flows, layers and dynamos
Paul Pružina, Nathanaël Schaeffer, David Cébron
Large regions of giant planets are thought to possess unstable thermal gradients stabilised by gradients in heavy-element composition. The fluid can then develop semi-convection, a…
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…
Mean zonal flows induced by weak mechanical forcings in rotating spheroids
David Cébron, Jérémie Vidal, Nathanaël Schaeffer +2
The generation of mean flows is a long-standing issue in rotating fluids. Motivated by planetary objects, we consider here a rapidly rotating fluid-filled spheroid, which is subjec…
Rotating double-diffusive convection in stably stratified planetary cores
Rémy Monville, Jérémie Vidal, David Cébron +1
In planetary fluid cores, the density depends on temperature and chemical composition, which diffuse at very different rates. This leads to various instabilities, bearing the name…
Precessing spherical shells: flows, dissipation, dynamo and the lunar core
David Cébron, Raphaël Laguerre, Jerome Noir +1
Precession of planets or moons affects internal liquid layers by driving flows, instabilities and possibly dynamos.The energy dissipated by these phenomena can influence orbital pa…
Diffusionless hydromagnetic modes in rotating ellipsoids: a road to weakly nonlinear models?
Jérémie Vidal, David Cébron, Nathanaël Schaeffer
We investigate free hydromagnetic eigenmodes of an incompressible, inviscid and ideal electrically conducting fluid in rotating triaxial ellipsoids. The container rotates with an a…
