Cosmic magnetic fields, including the fields of planets, stars, and galaxies, are believed to
be caused by dynamo action in moving electrically conducting fluids. While the theory and …

We study numerically an extensive set of dynamo models in rotating spherical shells,
varying all relevant control parameters by at least two orders of magnitude. Convection is …

Global scale magnetostrophic balance, in which Lorentz and Coriolis forces comprise the
leading-order force balance, has long been thought to describe the natural state of planetary …

Although the origin of Earth's and other celestial bodies' magnetic fields remains unknown,
we do know that the motion of electrically conducting fluids generates and maintains these …

The magnetic fields of planets and stars are thought to play an important role in the fluid
motions responsible for their field generation, as magnetic energy is ultimately derived from …

Detached shear layers in a rotating container, known as Stewartson layers, become
unstable for a critical shear measured by the Rossby number Ro⁠. To study rapidly rotating …

In fluid dynamics, the scaling behaviour of flow length scales is commonly used to infer the
governing force balance of a system. The key to a successful approach is to measure length …

We report on the electrical and thermal conductivity of liquid sodium at 400 K, calculated
using density functional theory with the local density approximation (LDA) and the Kubo …

Geostrophic jets propagating as Alfvén waves are shown to arise in a rapidly rotating
spherical shell permeated by a magnetic field among the transient motions set up by an …

Magnetic field generation and evolution in celestial bodies—the subject matter of the theory
of the dynamo—held Ya B Zeldovich's interest for years. Over the time since then, the study …
