Parker Problem in Hall Magnetohydrodynamics

Parker problem in Hall magnetohydrodynamics (MHD) is considered [1]. Poloidal shear into the toroidal flow generated by the Hall effect is incorporated. This is found to lead to a {\it 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 $1/x^3$) than that (like $1/x$) in the outer ideal MHD region.\\ \noindent [1] B.
