Destruction of large-scale magnetic field in nonlinear simulations of the shear dynamo
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2016-03-03)
The Sun's magnetic field exhibits coherence in space and time on much larger scales than the turbulent convection that ultimately powers the dynamo. In the past the α-effect (mean-field) concept has been used to model the ...
On the nature of the magnetic Rayleigh–Taylor instability in astrophysical plasma: the case of uniform magnetic field strength
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2016-07-28)
The magnetic Rayleigh–Taylor instability has been shown to play a key role in many astrophysical systems. The equation for the growth rate of this instability in the incompressible limit, and the most-unstable mode that ...
