Formation of a quasi-one-dimensional current sheet in the laboratory experiment and in the Earth's magnetotail

Petrukovich, A. A.; Artemyev, A. V.; Vasko, I. Y. +2 more

Two-dimensional current sheets (CSs) generated in the CS-3D laboratory device are considered. Results obtained in the laboratory experiment are compared with spacecraft observations of CSs in the Earth's magnetotail. The longitudinal and transverse CS structures, as well as CS evolution during the thinning process are studied. It is demonstrated t…

A possible mechanism of the enhancement and maintenance of the shear magnetic field component in the current sheet of the Earth's magnetotail

Malova, H. V.; Zelenyi, L. M.; Malykhin, A. Yu. +1 more

The influence of the shear magnetic field component, which is directed along the electric current in the current sheet (CS) of the Earth's magnetotail and enhanced near the neutral plane of the CS, on the nonadiabatic dynamics of ions interacting with the CS is studied. The results of simulation of the nonadiabatic ion motion in the prescribed mag…

Modeling of different scenarios of thin current sheet equilibria in the Earth's magnetotail

Malova, H. V.; Popov, V. Yu.; Zelenyi, L. M. +1 more

The Earth's magnetosphere is an open dynamic system permanently interacting with the solar wind, i.e., the plasma flow from the Sun. Some plasma processes in the magnetosphere are of spontaneous explosive character, while others develop rather slowly as compared to the characteristic times of plasma particle motion in it. The large-scale current s…
