Review of Pi2 Models
Keiling, Andreas; Takahashi, Kazue
More than half a century after the discovery of Pi2 pulsations, Pi2 research is still vigorous and evolving. Especially in the last decade, new results have provided supporting evidence for some Pi2 models, challenged earlier interpretations, and led to entirely new models. We have gone beyond the inner magnetosphere and have explored the outer ma…
Properties of Near-Earth Magnetic Reconnection from In-Situ Observations
Fuselier, S. A.; Lewis, W. S.
Many properties of magnetic reconnection have been determined from in-situ spacecraft observations in the Earth's magnetosphere. Recent studies have focused on ion scale lengths and have largely confirmed theoretical predictions. In addition, some interesting features of reconnection regions on electron scale lengths have been identified. These re…
Reconnection and Waves: A Review with a Perspective
Fujimoto, M.; Shinohara, I.; Kojima, H.
This review is intended to help prepare a new stage of wave studies in the context of magnetic reconnection. Various results that have accumulated would not let the two-dimensional, steady and laminar magnetic reconnection to remain as the standard model. Emphasis on three-dimensional, temporally varying, and turbulent effects is growing and this …
ARTEMIS Science Objectives
Russell, C. T.; Khurana, K. K.; Eastwood, J. P. +17 more
NASA's two spacecraft ARTEMIS mission will address both heliospheric and planetary research questions, first while in orbit about the Earth with the Moon and subsequently while in orbit about the Moon. Heliospheric topics include the structure of the Earth's magnetotail; reconnection, particle acceleration, and turbulence in the Earth's magnetosph…
Electron Physics of Asymmetric Magnetic Field Reconnection
Mozer, Forrest S.; Pritchett, Philip L.
There have been many significant advances in understanding magnetic field reconnection as a result of improved space measurements and two-dimensional computer simulations. While reviews of recent work have tended to focus on symmetric reconnection on ion and larger spatial scales, the present review will focus on asymmetric reconnection and on ele…
Non-adiabatic Ion Acceleration in the Earth Magnetotail and Its Various Manifestations in the Plasma Sheet Boundary Layer
Zelenyi, L. M.; Sauvaud, J. -A.; Owen, C. J. +5 more
Many physical phenomena in space involve energy dissipation which generally leads to charged particle acceleration, often up to very high energies. In the Earth magnetosphere energy accumulation and release occur in the magnetotail, namely in its Current Sheet (CS). The kinetic analysis of non-adiabatic ion trajectories in the CS region with finit…
Grad-Shafranov Reconstruction of Magnetic Flux Ropes in the Near-Earth Space
Lui, A. T. Y.
Electric currents permeate space plasmas and often have a significant component along the magnetic field to form magnetic flux ropes. A larger spatial perspective of these structures than from the direct observation along the satellite path is crucial in visualizing their role in plasma dynamics. For magnetic flux ropes that are approximately two-…
Understanding the Dynamics of Magnetic Reconnection Layer
Yamada, Masaaki
We review progress in understanding the dynamics of a typical magnetic reconnection layer by describing the historical development of theory and the recent findings and discoveries in space and laboratory plasmas. The emphasis is on the dynamics of electrons moving with respect to ions in the collision-free neutral sheet. We make a detailed compar…
