Few areas of geophysics are today progressing as rapidly as basic geomagnetism, which
seeks to understand the origin of the Earth's magnetism. Data about the present …

The magnetic fields of the planets, including the Earth, are generated by dynamo action in
their fluid cores. Numerical models of this process have been developed that solve the …

An accurate description of turbulent core convection is necessary in order to build robust
models of planetary core processes. Towards this end, we focus here on the physics of …

Rayleigh–Bénard convection in rotating spherical shells can be considered as a simplified
analogue of many astrophysical and geophysical fluid flows. Here, we use three …

Ocean worlds are prevalent in the solar system. Focusing on Enceladus, Titan, Europa, and
Ganymede, I use rotating convection theory and numerical simulations to predict ocean …

We numerically explore convection and general circulation of an ocean, encased in a
spherical shell of uniform thickness, heated from below by a spatially uniform heat flux, and …

The Earth's liquid outer core is stirred by thermal and compositional convection. In thermal
convection the buoyancy is due to temperature fluctuations, while in compositional …

In order to characterize the global circulation of the subsurface ocean of Jovian and
Saturnian moons, we analyse the properties of 21 three-dimensional simulations of …

Convection occurs ubiquitously on and in rotating geophysical and astrophysical bodies.
Prior spherical shell studies have shown that the convection dynamics in polar regions can …

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 …
