Scale Selection in the Stratified Convection of the Solar Photosphere
M. Kessar, D. W. Hughes, E. Kersale +2
We examine the role of stratification in determining the scale for turbulent anelastic convection. Motivated by the range of scales observed in convection at the solar photosphere,…
Nonaxisymmetric linear instability of cylindrical magnetohydrodynamic Taylor-Couette flow
Adam Child, Evy Kersalé, Rainer Hollerbach
We consider the nonaxisymmetric modes of instability present in Taylor-Couette flow under the application of helical magnetic fields, mainly for magnetic Prandtl numbers close to t…
The Nonlinear Evolution of Instabilities Driven by Magnetic Buoyancy: A New Mechanism for the Formation of Coherent Magnetic Structures
Evy Kersale, David W. Hughes, Steven M. Tobias
Motivated by the problem of the formation of active regions from a deep-seated solar magnetic field, we consider the nonlinear three-dimensional evolution of magnetic buoyancy inst…
Pressure- and magnetic shear- driven instabilities in rotating MHD jets
Evy Kersale, Pierre-Yves Longaretti, Guy Pelletier
We derive new stability criteria for purely MHD instabilities in rotating jets, in the framework of the ballooning ordering expansion. Quite unexpectedly, they involve a term which…
