Three-Layer Magnetoconvection
M. -K. Lin, L. J. Silvers, M. R. E. Proctor
It is believed that some stars have two or more convection zones in close proximity near to the stellar photosphere. These zones are separated by convectively stable regions that a…
Large-scale Dynamo Action Driven by Velocity Shear and Rotating Convection
David W. Hughes, Michael R. E. Proctor
By incorporating a large-scale shear flow into turbulent rotating convection, we show that a sufficiently strong shear can promote dynamo action in flows that in the absence of she…
Subcritical dynamos in shear flows
F. Rincon, G. I. Ogilvie, M. R. E. Proctor +1
Identifying generic physical mechanisms responsible for the generation of magnetic fields and turbulence in differentially rotating flows is fundamental to understand the dynamics…
Effects of fluctuation on alpha-omega dynamo models
Michael R. E. Proctor
We analyse the role of a fluctuating alpha-effect in alpha-omega dynamo models, and show that there is a mechanism for magnetic field generation, valid at large scale separation, d…
A self-sustaining nonlinear dynamo process in Keplerian shear flows
F. Rincon, G. I. Ogilvie, M. R. E. Proctor
A three-dimensional nonlinear dynamo process is identified in rotating plane Couette flow in the Keplerian regime. It is analogous to the hydrodynamic self-sustaining process in no…
On the relation between viscoelastic and magnetohydrodynamic flows and their instabilities
Gordon I. Ogilvie, Michael R. E. Proctor
We demonstrate a close analogy between a viscoelastic medium and an electrically conducting fluid containing a magnetic field. Specifically, the dynamics of the Oldroyd-B fluid in…
