The inner magnetosphere source of dawn-dusk electric field and magnetospheric dynamics

Advances in Space Research, 1997
Abstract The qualitative theory of the formation of inner magnetosphere dawn-dusk electric field based only on the assumption of the magnetostatic equilibrium in the asymmetric plasma trap was developed. The theory associates the generation of Region 1 field-aligned currents with the topology of magnetic field in the transition region where the ...

Storms in the Inner Magnetosphere

2010
The inner magnetosphere containing the plasmasphere, ring current and radiation belts is a key domain of magnetospheric storms from both physical and practical viewpoints. The growth, decay and asymmetries of the ring current are considered as main indicators of the large-scale storm evolution and the electron belts respond strongly to the storm ...

Energetic particle penetrations into the inner magnetosphere

Journal of Geophysical Research: Space Physics, 1980
Data from Explorer 45 (S³‐A) instruments have revealed characteristics of magnetospheric storm or substorm time energetic particle enhancements in the inner magnetosphere (L ≲5). The properties of the ion ‘nose’ structure in the dusk hemisphere are examined in detail.

Inner magnetosphere coupling

2016
The dynamics of the inner magnetosphere is strongly governed by the interactions between different plasma populations that are coupled through large-scale electric and magnetic fields, currents, and wave-particle interactions. Inner magnetospheric plasma undergoes self-consistent interactions with global electric and magnetic fields.

Drivers of the Inner Magnetosphere

2013
This paper addresses the role of the electric fields in the inner magnetosphere dynamics by reviewing observations and model results, especially whether the stormtime ring current intensification is generated by large-scale convection alone or together with substorm-associated variations.

Light ion concentrations in Jupiter's inner magnetosphere

Journal of Geophysical Research: Space Physics, 1982
In this paper, Voyager 1 plasma wave instrument observations of lightning‐generated whistlers are combined with Voyager 1 plasma instrument heavy ion (8 ≤ A/Z ≤ 64) charge concentrations to investigate the concentration of light ions (A/Z < 8) along the whistler propagation path.

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.

Magnetospheric Substorms and the Sources of Inner Magnetosphere Particle Acceleration

2013
The solution of the problem of the acceleration of relativistic electrons during magnetospheric storms requires the self-consistent analysis of the processes of the formation of the ring current and particle acceleration. The experimental proofs of the substorm particle acceleration before the beginning of the dipolarization provide the new aspects of ...

MHD eigenmodes in the inner magnetosphere

2006
Many ultra-low-frequency phenomena observed in the inner magnetosphere are attributed to magnetohydrodynamic (MHD) eigenmodes. We review theoretical investigations of the compressional and shear (Alfven) eigenmodes and the coupling between them. The properties of the eigenmodes are strongly controlled by the spatial variation of the Alfven speed ...

Energetic ions trapped in Saturn's inner magnetosphere

Planetary and Space Science, 2009
Abstract The low-energy magnetospheric measurement system (LEMMS) of the magnetosphere imaging instrument (MIMI) aboard the Cassini orbiter observed energetic ions and electrons during Saturn orbit insertion (SOI) of July 1, 2004. Salient features of the trapped ion fluxes observed in the L =2–4 R S region include the occurrence of two distinct ...
