Inner magnetosphere currents and their role in the magnetosphere dynamics

Physics and Chemistry of the Earth, Part C: Solar, Terrestrial & Planetary Science, 2000
Abstract The role of inner magnetosphere currents in the magnetopause dynamics is analyzed. The change of magnetopause position under the influence of inner magnetosphere magnetic field sources is analyzed. It is shown that the main source of such change may be an effective eastward ring current flowing near the inner edge of the plasma sheet.

Plasma boundaries in the inner magnetosphere

Journal of Geophysical Research: Space Physics, 1986
Plasma boundaries in the inner magnetosphere are investigated with measurements chiefly by the DE 1 and 2 spacecraft. The boundaries studied here are: (1) the low‐energy (or thermal) ion transition (LEIT) frequently observed at or near the conventional plasmapause density gradient, defined here as the outer boundary of observable, cold, isotropic light

Collective phenomena in the inner magnetosphere

Physics of Plasmas, 1999
The Earth’s magnetosphere exhibits substantial complexity in many of its physical properties. Particle populations wax and wane and magnetic fields fluctuate on virtually all observed time scales, from less than 1 minute to many days. Much of the variability of the magnetosphere and its interaction with the ionosphere can be ascribed to the phenomena ...

Saturn's ring current and inner magnetosphere

Nature, 1981
The Voyager 1 magnetic field observations at Saturn are shown in a graph. The departure of the oberved magnetic field from the field of a dipole is considered. The observed field magnitude is appreciable less than that of the model dipole at small radial distances and greater than the model dipole in the more distant magnetosphere.

Particle Acceleration in the Inner Magnetosphere

2013
Particle acceleration is an important consequence of eruptive or catastrophic configuration changes in space plasmas. It is also a feature associated with more persistent structures, such as thin boundary layers, which exhibit strong gradients, instabilities, and turbulence.

Magnetospheric substorms: An inner-magnetospheric modeling perspective

2002
Abstract Kilovolt electrons cause satellite anomalies through surface charging and frequently interfere with the operation of geosynchronous spacecraft. The Magnetospheric Specification Model was designed to specify kilovolt electron fluxes at and near synchronous orbit, and while it has seen limited operational use, its accuracy is not high.

The Inner Magnetosphere: A Review

Surveys in Geophysics, 1995
This paper addresses research achievements during roughly the period 1991–1993 pertaining to the inner magnetosphere including the radiation belts, plasmasphere, and ring current region. It also addresses issues concerning the magnetic fields, electrical currents, and particle precipitation properties that relate to this region of the solar-terrestrial

Inner Magnetospheric Modeling with the Rice Convection Model

Space Science Reviews, 2003
The Rice Convection Model (RCM) is an established physical model of the inner and middle magnetosphere that includes coupling to the ionosphere. It uses a many-fluid formalism to describe adiabatically drifting isotropic particle distributions in a self-consistently computed electric field and specified magnetic field.

Effect of magnetospheric convection on thermal plasma in the inner magnetosphere

Journal of Geophysical Research: Space Physics, 1994
The effects of E × B convection on the distribution of plasma parameters in the inner magnetosphere have been examined. Analytical solutions describing density distributions along convective trajectories in the equatorial plane have been found. These solutions suggest the following dependence of plasma concentration n on the magnetic field B along ...

Whistler mode noise in Jupiter's inner magnetosphere

Journal of Geophysical Research: Space Physics, 1978
The distinctive ‘hat shape’ of equatorial pitch angle distributions constructed from Pioneer 10 and 11 Jupiter observations of energetic electrons Ee > 21 MeV and Ee > 31 MeV at L = 3 is examined from the point of view of pitch angle diffusion by resonant interaction with a band‐limited spectrum of whistler mode noise.
