The Flapping Motion of Mercury's Magnetotail Current Sheet: MESSENGER Observations

open access: yesGeophysical Research Letters, 2020
The flapping motion of Mercury's magnetotail current sheet is investigated based on the observations of MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER). The typical flapping period in Mercury's magnetotail is much shorter (~13 s)

Disruption of magnetospheric current sheet by quasi-electrostatic field [PDF]

open access: yesAnnales Geophysicae, 2009
Recent observational evidence has indicated that local current sheet disruptions are excited by an external perturbation likely associated with the kinetic ballooning (KB) instability initiating at the transition region separating the dipole- and tail-

Magnetic configurations of the tilted current sheets in magnetotail [PDF]

open access: yesAnnales Geophysicae, 2008
In this research, the geometrical structures of tilted current sheet and tail flapping waves have been analysed based on multiple spacecraft measurements and some features of the tilted current sheets have been made clear for the first time.

Effect of guide field on three dimensional electron shear flow instabilities in collisionless magnetic reconnection

open access: yes, 2015
We examine the effect of an external guide field and current sheet thickness on the growth rates and nature of three dimensional unstable modes of an electron current sheet driven by electron shear flow.

Particle acceleration in 3D single current sheets formed in the solar corona and heliosphere: PIC approach [PDF]

open access: yes, 2015
Acceleration of protons and electrons in a reconnecting current sheet (RCS) is investigated with the test particle and particle-in-cell (PIG) approaches in a 3D magnetic topology. PIG simulations confirm a spatial separation of electrons and protons with

Forced magnetic reconnection and plasmoid coalescence: I - MHD Simulations [PDF]

open access: yes, 2019
Forced magnetic reconnection, a reconnection event triggered by external perturbation, should be ubiquitous in the solar corona. Energy released during such cases can be much greater than that which was introduced by the perturbation.

The heliospheric current sheet [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2001
The heliospheric current sheet (HCS) is the boundary between open oppositely directed magnetic field lines which commonly originate as the outward extension of the solar magnetic dipole. The dipole tilt, the rotation of the Sun, and the outward propagation of the solar wind cause peaks and valleys in the current sheet which spiral outward.

A Bifurcated Reconnecting Current Sheet in the Turbulent Magnetosheath

open access: yesMagnetochemistry
We report the Magnetospheric Multiscale (MMS) observation of a bifurcated reconnecting current sheet in Earth’s dayside magnetosheath. Typical signatures of the ion diffusion region, including sub-Alfvénic demagnetized ion outflow, super-Alfvénic ...
