Magnetohydrodynamics dynamical relaxation of coronal magnetic fields : IV. 3D tilted nulls
(2013-09-12) - Journal articleIn this paper we study current accumulations in 3D "tilted" nulls formed by a folding of the spine and fan. A non-zero component of current parallel to the fan is required such that the null's fan plane and spine are not ... -
Magnetohydrodynamics dynamical relaxation of coronal magnetic fields : III. 3D spiral nulls
(2012-06) - Journal articleContext: The majority of studies on stressed 3D magnetic null points consider magnetic reconnection driven by an external perturbation, but the formation of a genuine current sheet equilibrium remains poorly understood. ... -
Inhomogeneous magnetic fields in the solar atmosphere
(University of St Andrews, 1984) - ThesisThe magnetic field in the solar atmosphere is highly inhomogeneous. In the photosphere, the field is concentrated into intense flux tubes and the coronal magnetic field consists of many loops and regions of open field. ... -
The structure, stability and interaction of geophysical vortices
(University of St Andrews, 2013-06-28) - ThesisThis thesis examines the structure, stability and interaction of geophysical vortices. We do so by restricting our attention to relative vortex equilibria, or states which appear stationary in a co-rotating frame of ... -
Two-dimensional magnetohydrodynamic turbulence in the small magnetic Prandtl number limit
(2012-07-01) - Journal articleIn this paper we introduce a new method for computations of two-dimensional magnetohydrodynamic (MHD) turbulence at low magnetic Prandtl number $\Pra=\nu/\eta$. When $\Pra \ll 1$, the magnetic field dissipates at a scale ...
