Ion- and electron-acoustic solitons and double layers in multi-component space plasmas
Lakhina, G. S.; Singh, S. V.; Kakad, A. P.
A general model for the ion- and electron-acoustic solitons and double layers in a multi-component unmagnetized plasma consisting of background electrons, counter-streaming electron beams and ions is discussed. The model is based on the multi-fluid equations and the Poisson equation, and uses the Sagdeev pseudo-potential techniques. For identical …
Kink-like mode of a double gradient instability in a compressible plasma current sheet
Korovinskiy, D. B.; Semenov, V. S.; Erkaev, N. V. +4 more
A linear MHD instability of the electric current sheet, characterized by a small normal magnetic field component, varying along the sheet, is investigated. The tangential magnetic field component is modeled by a hyperbolic function, describing Harris-like variations of the field across the sheet. For this problem, which is formulated in a 3D domai…
Structure and kinetic properties of slow-mode shocks associated with magnetic reconnection in the near-Earth magnetotail
Yuan, Zhigang; Zhou, Meng; Lin, Xi +3 more
We study the structure and kinetic properties of slow-mode shocks near the plasma sheet boundary layer (PSBL) associated with magnetic reconnection by Cluster observation. The presence of slow-mode shocks is confirmed by traditional Rankine-Hugoniot (RH) analysis and Monte-Carlo shock fitting method. The Walén analysis, applied to the tailward flo…
Generic procedure for designing and implementing plan management systems for space science missions operations
Chaizy, P. A.; Dimbylow, T. G.; Hapgood, M. A. +1 more
This paper is one of the components of a larger framework of activities whose purpose is to improve the performance and productivity of space mission systems, i.e. to increase both what can be achieved and the cost effectiveness of this achievement. Some of these activities introduced the concept of Functional Architecture Module (FAM); FAMs are b…
Science operations planning expertise: A neglected component of mission design
Chaizy, P. A.; Dimbylow, T. G.; Hapgood, M. A. +1 more
In this paper, Science Operations Planning Expertise (SOPE) is defined as the expertise that is held by people who have the two following qualities. First they have both theoretical and practical experience in operations planning, in general, and in space science operations planning in particular. Second, they can be used, on request and at least,…
Multi-point observations of earthward fast flow in the plasma sheet by virtual satellites located in the MHD simulation domain
Kondoh, Koji; Shimizu, Tohru; Ugai, Masayuki
Time profiles of some physical values in earthward fast flows in the plasma sheet are observed at three dimensionally different positions by employing virtual satellites located in the three-dimensional magnetohydrodynamic simulation domain, and these simulations are done on the basis of the spontaneous fast reconnection model. In the spontaneous …
