Magnetoconvection in a spherical shell: Equatorial symmetry during the transition from the weak- to the strong-field regime
Luke J. Gostelow, Robert J. Teed
At small but supercritical Rayleigh numbers, simulations of dynamos in spherical shells often separate into two broad regimes characterised either by their relative magnetic field…
Influence of Boundary Conditions and Heating Modes on the Onset of Columnar Convection in Rotating Spherical Shells
William Seeley, Francesca Coke, Radostin Simitev +1
We investigate the linear onset of thermal convection in rotating spherical shells with a focus on the influence of mechanical boundary conditions and thermal driving modes. Using…
Local three-dimensional simulations of the convective overstability in protoplanetary discs
Robert J. Teed, Henrik N. Latter
At certain radii protoplanetary discs may sustain a form of oscillatory convection (`convective overstability'; COS) due to localised adverse entropy gradients. The resulting hydro…
Scaling of strong-field spherical dynamos
Robert J. Teed, Emmanuel Dormy
Numerical experiments of dynamo action designed to understand the generation of Earth's magnetic field produce different regime branches identified within bifurcation diagrams. Not…
