Reconnection in the magnetotail

Space Science Reviews, 1979
The ion tearing mode is considered as the only mechanism capable of initiating reconnection processes in the equilibrium plasma sheet whose scale considerably exceeds the ion Larmor radius. The paper gives a brief review of linear theory of the tearing mode instability that allows the onset of its development to be determined.

Plasmoids in Saturn's magnetotail

Journal of Geophysical Research: Space Physics, 2008
Plasmoids in Saturn's magnetotail are identified by a reversal (northward turning) of the normally southward component of the magnetic field across the tail current sheet. Three large plasmoids have been identified by the Cassini magnetometer, one near 0300 local time at a planet‐centered distance of 44 RS and two near midnight at 48–49 RS.

The Jovian magnetotail

Advances in Space Research, 1986
The current understanding of the plasma, magnetic field, and plasma wave characteristics of the near and distant Jovian magnetotail is discussed. The properties of these two regions are compared, with particular emphasis given to the data on the distant tail obtained by Voyager 2.

Magnetotail energy storage and the variability of the magnetotail current sheet

1984
The antiparallel field configuration in the earth magnetotail is a prime location to search for the important astrophysical process known as magnetic reconnection. The magnetic evidence that reconnection occurs in the earth's magnetotail is that the energy of the tail invariably decreases at the time of global substorm onsets, and that an increased ...

Particle dynamics and currents in the magnetotail

Astrophysics and Space Science, 1988
This paper is a brief summary of our studies of magnetotail phenomena, based on the motion of charged particles and on electric currents. Theory and satellite data have been used together to obtain quantitative understanding.

Macroinstabilities of the Magnetotail

1979
There is evidence supporting the view that substorms are initiated by an instability. The present paper starts out from the assumption that the unstable process is an instability of the magnetotail. The stability theory of the tail is summarized and the major predictions are described. It is argued that the spontaneous reconnection (tearing) picture is

The Earth's Dynamic Magnetotail

Space Science Reviews, 2000
Geomagnetic field lines that are stretched on the nightside of the Earth due to reconnection with the interplanetary magnetic field constitute the Earth's magnetotail. The magnetotail is a dynamic entity where energy imparted from the solar wind is stored and then released to generate disturbance phenomena such as substorms. This paper gives an updated

Relaxation of magnetotail plasmas

Journal of Geophysical Research: Space Physics, 1987
A quasi‐thermodynamic model is presented for the relaxation of magnetotail plasmas during substorms, followed by quiet times. It is proposed that the plasma relaxes to a state of low‐potential energy subject to a small number of global constraints.

Substorm dynamics in the magnetotail

Physica Scripta, 1998
The large-scale dynamic evolution of the magnetotail in relation to substorms is most commonly understood and described in terms of magnetic reconnection, neutral line formation, and plasmoid ejection into the distant tail, as well as current disruption and diversion in the inner tail.

Reconnection in Earth's magnetotail

Science, 2018
Plasma Astrophysics Magnetic fields in plasmas can rapidly rearrange themselves in a process known as magnetic reconnection, which releases energy and accelerates particles. Torbert et al. used the Magnetospheric Multiscale (MMS) mission to probe a reconnection event in Earth's magnetotail—the region of plasma downstream from the planet as it moves ...
