Quasi-adiabatic dynamics of ions in a bifurcated current sheet

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

The study is devoted to ion dynamics in bifurcated current sheets with a two-peak current-density distribution observed in the Earth's magnetotail and solar wind. The ion motion is described by a Hamiltonian system with two degrees of freedom. The presence of a small parameter κ characterizing the ratio between the amplitudes of the normal and tan…
