Equations for Nonlinear MHD Convection in Shearless Magnetic Systems
Abstract
A closed set of reduced dynamic equations is derived that describe nonlinear lowfrequency flute MHD convection and resulting nondiffusive transport processes in weakly dissipative plasmas with closed or open magnetic field lines. The equations obtained make it possible to selfconsistently simulate transport processes and the establishment of the selfconsistent plasma temperature and density profiles for a large class of axisymmetric nonparaxial shearless magnetic devices: levitated dipole configurations, mirror systems, compact tori, etc. Reduced equations that are suitable for modeling the longterm evolution of the plasma on time scales comparable to the plasma lifetime are derived by the method of the adiabatic separation of fast and slow motions.

The shear Alfv{acute e}n wave in a resistive plasma with a shearless magnetic field
In this Brief Communication, the time development of the shear Alfv{acute e}n wave in a resistive magnetohydrodynamic plasma is treated. The analysis is restricted to a pressureless plasma confined in a planar sheet pinch with a constant equilibrium magnetic field directed parallel to the magnetic surface wave vector. The equilibrium mass density depends on the spatial coordinate orthogonal to the planar magnetic surfaces. Under these conditions, the shear Alfv{acute e}n mode decouples from the compressional Alfv{acute e}n mode. The time behavior of the wave fields is governed by a secondorder scalar partial differential equation. Laplace transform techniques are used tomore » 
Particle simulations of currentdriven drift waves in shearless and sheared magnetic fields
The nonlinear behavior of the collisionless currentdriven drift instability in shearless and sheared magnetic fields is studied by means of particle simulation. Electrostatic models with guiding center electrons and full dynamic ions are used in both twoandonehalf and three dimensions. The electron current (J/sub parallel/), in the direction parallel to the magnetic field but perpendicular to the density gradient in the x direction, is maintained throughout the simulation. Instability thresholds, growth rates, real frequency spectra, and mode structures observed in the simulation are in good agreement with theory. Saturation of the unstable modes occurs by a flattening of the electronmore » 
Nonlinear astrophysical dynamos: The solar cycle as a nonlinear oscillation of the general magnetic field driven by the nonlinear dynamo and the associated modulation of the differentialrotationglobalconvection system
The nonlinear reaction of the magnetic field on the fieldgenerating fluid motions in the dynamo process is formulated within the framework of the dynamo equation of the mean magnetohydrodynamics. If this nonlinear reaction mechanism is working in the process of the solar cycle, the differentialrotationglobalconvection system operating the solar dynamo must be undergoing an oscillatory modulation associated with the solar cycle. As observable evidences of the operation of the dynamo process, the extended period of near absence of the surface activity of the Sun in the 17th to 18th centuries, the rapid resumption of the magnetic activity to the normalmore »
