项目摘要
Earth's magnetotail is the elongated portion of Earth's magnetic field formed on the night (or anti-sunward) side of the magnetosphere. This region is characterized by energy release that accompanies the reconfiguration (aka 'reconnection') of oppositely directed magnetic field lines. In the process, magnetic field energy is converted to plasma kinetic and thermal energy. The researchers will perform computer simulations to investigate the roles played by several types of magneto-hydrodynamical instabilities. This work will contribute to fundamental knowledge of plasma discontinuities and magnetic reconnection. These processes are pertinent not only to Earth, but also to solar, planetary and stellar magnetospheres, as well as fusion devices and laboratory reconnection experiments. Knowledge derived from the work will advance understanding and modeling of space weather. Educational benefits will be provided in the form of hands-on research training for student summer interns.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
地球磁尾是地球磁场的拉长部分,形成在磁层的夜晚(或反太阳)一侧。该区域的特征在于伴随着反向磁场线的重新配置(又名“重连”)的能量释放。在该过程中,磁场能量被转换成等离子体动能和热能。研究人员将进行计算机模拟,以研究几种类型的磁流体动力学不稳定性所扮演的角色。这项工作将有助于等离子体不连续性和磁场重联的基础知识。这些过程不仅与地球有关,而且与太阳、行星和恒星磁层以及聚变装置和实验室重连实验有关。从这项工作中获得的知识将促进对空间气象的理解和建模。该奖项反映了NSF的法定使命,并被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估来支持。
