Magnetic Weibel field generation in thin collisionless current sheets in reconnection in space plasma
In collisionless reconnection in space plasma like the magnetospheric tail or magnetopause current layer, magnetic fields can grow from thermal level by the action of the non-magnetic Weibel instability driven in thin (∆ < few λi) current layers by the counter-streaming electron inflow from the ‘ion diffusion’ (ion inertial Hall) region into the inner current (electron inertial) region from whe...
متن کاملCollisionless magnetic reconnection with arbitrary guide-field
A new set of reduced equations governing two-dimensional, two-fluid, collisionless magnetic reconnection with arbitrary guide-field is derived. These equations represent a significant advance in magnetic reconnection theory, since the existing reduced equations used to investigate collisionless reconnection are only valid in the large guide-field limit. The new equations are used to calculate t...

متن کاملDevelopments in the theory of collisionless reconnection in magnetic configurations with a strong guide field
We review some recent results that have been obtained in the investigation of collisionless reconnection in two dimensional magnetic configurations with a strong guide field in regimes of interest for laboratory plasmas. First we adopt a two-fluid dissipationless plasma model where the plasma evolution is described by the advection of two Lagrangian invariant fields. Then, we show that an analo...
متن کاملChaos-induced resistivity of collisionless magnetic reconnection in the presence of a guide field
It is one of the most puzzling problems in astrophysics to understand the anomalous resistivity in collisionless magnetic reconnection that is believed extensively to be responsible for the energy release in various eruptive phenomena. The magnetic null point in the reconnect current sheet, acting as a scattering center, can lead to chaotic motions of particles in the current sheet, which is on...
