OSTI ID:5476237
Results obtained from solving Maxwell's and Vlasov's equations to obtain the electrical structure of the sheath that separates magnetospheric-particle populations of different densities and temperatures. It is shown that for reasonable magnetospheric plasma populations an electric potential difference of several kilovolts exists across such a boundary. This potential can serve as the necessary EMF for the auroral current circuit. Ths colocation between a magnetospheric plasma boundary and a discrete aurora is a natural consequence of this picture.
