Solitary structures with ion and electron thermal anisotropy

Murchana Khusroo, Madhurjya P Bora2015年Plasma Physics and Controlled FusionIF 2.2出版社

The formation of electrostatic solitary structures is analysed for a magnetised plasma with ion and electron thermal anisotropies. The ion thermal anisotropy is modelled with the help of the Chew–Goldberger–Low (CGL) double adiabatic equations of state while the electrons are treated as inertia-less species with an anisotropic bi-Maxwellian velocity distribution function. A negative electron thermal anisotropy is found to help form large amplitude solitary structures which are in agreement with observational data.

静電孤立構造の形成を、イオンおよび電子の熱異方性を有する磁化プラズマについて解析する。イオンの熱異方性は、Chew–Goldberger–Low(CGL)二重断熱状態方程式を用いてモデル化し、電子は異方性のあるbi-Maxwellian速度分布関数を持つ無慣性種として扱う。負の電子熱異方性は、観測データと一致する大振幅の孤立構造の形成に寄与することが見出される。
