Plasma flow in the magnetosphere.
We have constructed a mathematical model of the magnetosphere in which a large-scale uniform electric field, representing plasma flow from the tail, is superimposed on the geomagnetic field. InExpand

An observation of transient variations in the magnetospheric boundary position
The purpose of this Letter is to present data indicating the existence of long-period large-amplitude variations in the radial positions of the magnetopause on the sunlit side of the earth. DuringExpand

Solar wind and solar energetic particles: Properties and interactions
This paper reviews findings since 1966 about the properties of the interplanetary magnetic field; the solar wind plasma; solar wind interactions with the earth, the moon, Mars, and Venus; and theExpand

An empirical evaluation of radial diffusion coefficients for electrons of 50–100 kev from L = 4 to L = 7
Empirical values for radial diffusion coefficients have been calculated for electrons in the range 50–100 kev from L = 4 to L = 7 on the basis of equilibrium fluxes determined from Explorer 12 data.Expand

Discussion of paper by M. P. Nakada and G. D. Mead, ‘Diffusion of protons in the outer radiation belt’
Nakada and Mead [1965] have presented calculations of proton inward diffusion rates in the outer magnetosphere based on a diffusion mechanism originally proposed by Kellogg [1959] and applied inExpand

Synchrotron radio emission from Uranus and Neptune
Abstract A number of charged-particle radiation belt models for Uranus and Neptune are postulated, and the synchrotron emission spectrum for each is calculated over the frequency range 18.75 to 2400Expand

A revised (B, L) coordinate system to allow for distention of the magnetosphere by a symmetric ring current
The McIlwain (B, L) coordinate system for describing physical points within the magnetosphere is modified to take account of magnetospheric distortions arising from symmetric ring currents, theirExpand
