The work shows that a single elongated island immersed in the quasi-neutral current sheet makes it MHD unstable. Typical values of growth rate are found to be several per cent of inverse Alfven time for broad sheets. Hall dynamics greatly enhance instability and growth rate reaches one-tenth of ion cyclotron frequency when sheet width is comparable to ion inertia length. A weak square-root dependence of increment on island width and length is derived both from numerical simulation and…

Collapse of the neutral current sheet and reconnection at micro-scales

Abstract Reconnection physics at micro-scales is investigated in an electron magnetohydrodynamics frame. A new process of collapse of the neutral current sheet is demonstrated by means of analytical

Hall dynamics and resistive tearing instability

The stability of the neutral current sheet is analyzed in the frame of Hall dynamics. The problem is treated analytically and results are verified by numerical processing. A new version of tearing

Hall current effect on tearing mode instability

From a linear 2-D eigenmode analysis, we found that the Hall current effect on collisional tearing mode instability becomes important for the thin magnetic reversal layer whose width is comparable to

Coalescence instability of magnetic islands

The stability of a periodic magnetic island structure using the ideal magnetohydrodynamic equations has been investigated. An instability is found which describes the tendency toward coalescence of

Fast impulsive reconnection and current sheet intensification due to electron pressure gradients in semi‐collisional plasmas

A numerical simulation of forced reconnection and current sheet growth due to inward boundary flows in semi-collisional plasmas is presented, and contrasted with the results of an incompressible

Experimental study of lower-hybrid drift turbulence in a reconnecting current sheet

The role of turbulence in the process of magnetic reconnection has been the subject of a great deal of study and debate in the theoretical literature. At issue in this debate is whether turbulence is

The magnetohydrodynamics of current sheets

A universal phenomenon in cosmic plasmas is the creation of sheets of intense current near X-type neutral points (where the magnetic field vanishes). These sheets are important as sites where the

Open and closed magnetospheric tail configurations and their stability

The asymptotic theory valid for magnetospheric tail configurations that vary only weakly in the antisolar direction is used to derive a number of explicit properties. The conditions under which the

Magnetic reconnection driven by the coalescence instability

A detailed study of magnetic reconnection at an X point driven by the coalescence instability is presented. In particular, the effects of plasma compressibility and the magnitude of the toroidal

Electron magnetohydrodynamic simulations of magnetic island coalescence

The role of electrons in driving magnetic island coalescence in the electron magnetohydrodynamic limit is investigated. In particular, the dependence of the coalescence time tc(f) (defined as the

Transition to whistler mediated magnetic reconnection

The transition in the magnetic reconnection rate from the resistive magnetohydrodynamic (MHD) regime where the Alfven wave controls reconnection to a regime in which the ions become unmagnetized and
