Ohmic and viscous damping of inner core translational oscillations
Paolo Personnettaz, David Cébron, Nathanaël Schaeffer +2
Large earthquakes can trigger translational oscillations of Earth's inner core (Slichter modes), yet their damping remains uncertain. Using simulations, we quantify viscous and Ohm…
Magnetohydrodynamic drag on an oscillating sphere in a rotating spherical cavity
David Cébron, Paolo Personnettaz
Oscillating-sphere drag is a classical fluid-mechanics problem, yet no theory simultaneously accounts for confinement, rotation, viscosity and magnetic fields. We consider a conduc…
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…
