ABSTRACT
The Parker problem in Hall magnetohydrodynamics (MHD) is considered. Poloidal shear superposed on the toroidal ion flow associated with the Hall effect is incorporated. This is found to lead to a triple deck structure for the Parker problem in Hall MHD, with the magnetic field falling off in the intermediate Hall-resistive region more steeply (like 1/x3) than that (like 1/x) in the outer ideal MHD region.

    The latitude-time distribution of sunspot groups violating Hale polarity rule is considered for 1988–2004. This distribution exhibits a cyclic behavior similar to the general 11-year sunspot-activity cycle. The relative number of violating groups is used to estimate the ratio of the...

    Toroidal electron plasmas have remained less explored due to their poor confinement properties. Their equilibrium, stability, and confinement properties are therefore not entirely understood and continue to remain a topic of intense ongoing research. Large aspect-ratio theory suggests poor...

    Poloidal symmetry breaking in toroidal plasmas causes a damping of poloidal rotation and toroidal symmetry breaking a damping of toroidal rotation. These torques are transmitted by the magnetic field to the outside world. An upper limit exists on the torque that can be transmitted by magnetic...

    Particle transport in a toroidal plasma confinement device is shown to be nondiffusive when magnetic chaos is present. A phenomenological fit to density profiles gives a diffusion constant and also a pinch velocity directed up the density gradient. We show that the combination of diffusion and...

    The force balance, or equilibrium, of an axisymmetric toroidal plasma with a scalar pressure can be relatively simply calculated. However, equilibrium calculations present fundamental difficulties when either the geometry or the plasma forces are more complicated. Many of these issues, such as...
