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…
