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…

Planetary dynamos driven by semiconvection in stably stratified layers
Paul Pružina, David Cébron, Nathanaël Schaeffer
Stably stratified fluid layers are common in gaseous planets, stellar interiors, and planetary cores, and have long been considered incapable of sustaining dynamo action. Here, we…
