ELECTRON RINGS. “These relativistic electron fluxes show sharp dropouts and enhancements in response to the varying geomagnetic activity, and their dynamics is key to space weather, as these electrons pose a hazard to satellites in Earth orbit. Their rapid drift motion around the Earth is largely controlled by the magnetic field geometry, in contrast to the cold particles that are guided both by the electric and magnetic fields.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

INNER MAGNETOSPHERE. “The electron acceleration and loss processes are strongly dependent on the electric field structure and the wave-particle interactions in the inner magnetosphere.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

PARTICLE VORTEX. “The variety of processes bringing particles into the inner magnetosphere, the fact that the quasi-dipolar field allows trapping of the particles to closed drift orbits, and the relatively low collision frequencies that keep the system from obtaining thermal equilibrium all contribute to the complexity and variability of the inner magnetosphere plasma populations.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

PLASMA POPULATIONS. “It is important to note that the dynamic processes all occur on time scales that are short compared to collision times, which means that the plasma populations can retain their characteristics without being thermalized, and that the plasma distribution functions can significantly deviate from simple Maxwellians. Figure 4 shows the key plasma populations in the magnetosphere.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

“FIGURE 4. Inner magnetosphere plasma populations. The outer van Allen belt, the ring current, and the plasmasphere are colocated within the inner magnetosphere trapping region. The plasma sheet in the closed field line region extends to the dayside magnetopause and to the distant nightside tail.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

VAST ENERGY SOUP. “Energy, momentum, and plasma enter the magnetosphere both via magnetic reconnection at the magnetospheric boundaries in regions where the interplanetary and terrestrial fields are antiparallel and via viscous interactions along the boundary.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn
