The convective instability of a Maxwell-Cattaneo fluid in the presence of a vertical magnetic field
I. A. Eltayeb, D. W. Hughes, M. R. E. Proctor
We study the instability of a Bénard layer subject to a vertical uniform magnetic field, in which the fluid obeys the Maxwell-Cattaneo (MC) heat flux-temperature relation. We exten…
Vortex disruption by magnetohydrodynamic feedback
Julian Mak, Stephen D. Griffiths, D. W. Hughes
In an electrically conducting fluid, vortices stretch out a weak, large-scale magnetic field to form strong current sheets on their edges. Associated with these current sheets are…
Shear instabilities in shallow-water magnetohydrodynamics
Julian Mak, Stephen D. Griffiths, D. W. Hughes
Within the framework of shallow-water magnetohydrodynamics, we investigate the linear instability of horizontal shear flows, influenced by an aligned magnetic field and stratificat…
The alpha-effect in rotating convection: a comparison of numerical simulations
D. W. Hughes, M. R. E. Proctor, F. Cattaneo
Numerical simulations are an important tool in furthering our understanding of turbulent dynamo action, a process that occurs in a vast range of astrophysical bodies. It is importa…
The mean electromotive force resulting from magnetic buoyancy instability
C. R. Davies, D. W. Hughes
Motivated both by considerations of the generation of large-scale astrophysical magnetic fields and by potential problems with mean magnetic field generation by turbulent convectio…
The effects of flux transport on interface dynamos
J. Mason, D. W. Hughes, S. M. Tobias
The operation of an interface dynamo (as has been suggested for the Sun and other stars with convective envelopes) relies crucially upon the effective transport of magnetic flux be…
