Particle Acceleration in the Magnetotail and Aurora

Zelenyi, L. M.; Baker, D. N.; Artemyev, A. V. +3 more

This paper deals with acceleration processes in the magnetotail and the processes that enhance particle precipitation from the tail into the ionosphere through electric fields in the auroral acceleration region, generating or intensifying discrete auroral arcs. Particle acceleration in the magnetotail is closely related to substorms and the occurr…

Magnetic Reconnection in the Solar Wind

Gosling, J. T.

It is only within the last 5 years that we have learned how to recognize the unambiguous signature of magnetic reconnection in the solar wind in the form of roughly Alfvénic accelerated plasma flows embedded within bifurcated magnetic field reversal regions (current sheets). This paper provides a brief overview of what has since been learned about…

Anisotropy in Space Plasma Turbulence: Solar Wind Observations

Horbury, T. S.; Chen, C. H. K.; Wicks, R. T.

The local magnetic field induces many types of anisotropy in plasma turbulence, changing the rate of energy transfer and affecting the propagation of energetic particles. It is challenging to measure this anisotropy in the solar wind due to the limited number of sampling points and measurement difficulties and many aspects remain poorly understood…

Ion Acceleration at the Earth's Bow Shock

Möbius, E.; Scholer, M.; Burgess, D.

The Earth's bow shock is the most studied example of a collisionless shock in the solar system. It is also widely used to model or predict the behaviour at other astrophysical shock systems. Spacecraft observations, theoretical modelling and numerical simulations have led to a detailed understanding of the bow shock structure, the spatial organiza…

Scalings, Cascade and Intermittency in Solar Wind Turbulence

Carbone, Vincenzo

Investigating in situ fluctuations in the interplanetary space, offers us a unique challenge to study scaling properties in a turbulent medium which cover a wide range of scales. This includes not only the inertial range, where turbulence can be described within a fluid-like approach, but also the high-frequency region, where a kinetic approach is…
