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…
Did lunar tides sustain the early Earth's dynamo?
Jérémie Vidal, David Cébron
Geological data show that, early in its history, the Earth had a large-scale magnetic field with an amplitude comparable to the one of the present geomagnetic field. However, its o…
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…
Geophysical flows over topography, a playground for laboratory experiments
Jérémie Vidal, Jérôme Noir, David Cébron +4
Physicists face major challenges in modelling multi-scale phenomena that are observed in geophysical flows (e.g. in the Earth's oceans and atmosphere, or liquid planetary cores). I…
