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.

Implosion in the Magnetotail

1978
Undoubtedly, the most lively manifestation of the dynamic nature of the earth’s magnetosphere is the auroral break-up. The magnetospheric phenomena that are associated with this explosive release of energy have been the aim of intense research efforts in recent years, and the term magnetospheric substorm has been introduced to designate these phenomena

Ion streams in the magnetotail

Journal of Geophysical Research: Space Physics, 1981
Ion mass spectrometer observations of low‐temperature streaming plasmas in the earth's magnetotail are reported. Measurements in the energy per charge range 0 ≤E/q ≤17 keV/e were made at geocentric radial distances <23 RE from the ISEE 1 spacecraft.

Currents in the Earth's magnetotail

1984
Currents in the earth's magnetotail are detected with the plasma instrumentation on board the ISEE-1 spacecraft. Field-aligned currents directed into and out of the ionosphere are found in the boundary layer of the plasma sheet. Typical current densities are in the range of 5 x 10-9 to 5 x 10-8 A/m2.

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.

On the complexity of the Earth’s magnetotail

AIP Conference Proceedings, 2007
The Earth’s magnetotail dynamics shows several features that resemble those of a complex system. Here, after a brief review of some recent results and findings pointing towards the occurrence of dynamical complexity, we introduce a simple fully stochastic model for the statistical features of the magnetic field fluctuations in a quiet magnetotail ...

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 ...
