Energy injection, transport, and dissipation in Earth's magnetosphere

Cao, Jinbin; Fu, Huishan

The Earth's magnetosphere is a region occupied by many artificial satellites, and also is a region that spacecraft must cruise during the deep-space exploration. In this sense, the Earth's magnetosphere is closely related to human activity and is a candidate for us to expand our living space. Generally, the Earth's magnetosphere can preclude most …

New method for determining central axial orientation of flux rope embedded within current sheet using multipoint measurements

Chen, Tao; Li, ZhaoYu; Yan, GuangQing

A new method for determining the central axial orientation of a two-dimensional coherent magnetic flux rope (MFR) via multipoint analysis of the magnetic-field structure is developed. The method is devised under the following geometrical assumptions: (1) on its cross section, the structure is left-right symmetric; (2) the projected structure veloc…

Altitude of the upper boundary of AAR based on observations of ion beams in inverted-V structures: A case study

Xie, Lun; Parks, George; Cui, YanBo +5 more

Outflowing ion beams forming four successive inverted-V structures in the energy-time spectrograms of H+, He+, and O+ were observed at an altitude of 3.4 RE by Cluster satellites travelling above the auroral acceleration region (AAR) in the southern hemisphere on February 14, 2001. Energization by negative U-shaped potential structures in the AAR …

Some properties of field-aligned electron events in high-altitude polar regions

Zhang, ZiYing; Shi, JianKui; Zhou, MingQuan +2 more

Using data from the Cluster spacecraft from January 2003 to December 2004, we perform a statistical study on some properties of the field-aligned electron (FAE) events and interplanetary magnetic field (IMF) By dependence of FAE events with different durations in high-altitude polar regions. A total of 1335 FAE events were observed by the C3 space…

Case study of small scale polytropic index in the central plasma sheet

Cao, JinBin; Wang, Jing; Yang, JunYing +8 more

This paper studies the effective polytropic index in the central plasma sheet (CPS) by using the method of Kartalev et al. (2006), which adopts the denoising technique of Haar wavelet to identify the homogeneous MHD Bernoulli integral (MBI) and has been frequently used to study the polytropic relation in the solar wind. We chose the quiet CPS cros…
