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.

Saturn's Magnetosphere, Rings, and Inner Satellites

Science, 1980
Our 31 August to 5 September 1979 observations together with those of the other Pioneer 11 investigators provide the first credible discovery of the magnetosphere of Saturn and many detailed characteristics thereof. In physical dimensions and energetic charged particle population, Saturn's magnetosphere is intermediate between those of ...

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 ...

The Inner Magnetosphere Imager mission

Space Programs and Technologies Conference and Exhibit, 1993
Scientists have assembled an incomplete picture of the global composition and dynamics of the Earth’s magnetosphere in spite of 30 years of in situ measurements. Imaging the magnetosphere from space will enable scientists to better understand the global shape of the inner magnetosphere, its components, and processes.

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 ...

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

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.

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

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.

Inflation of the Inner Magnetosphere

1968
Frequently, the inner magnetosphere between L = 2 and L = 6 receives a large influx of energy. In the form of large numbers of charged particles or as an increase in the particle temperature, the energy enters the magnetosphere and it weakens and distorts the magnetic field through diamagnetism and drift motions of the charged particles.
