在大学实验室中检查磁层顶的位置
Examining the Location of the Magnetopause in an Undergraduate Lab
摘要：
将当前的研究领域整合到本科物理实验室可能是一项艰巨的任务。磁层顶的位置是一个不需要事先接触空间物理学就可以研究的问题。磁层顶的位置可以看作是太阳风的动压和磁层的磁压之间的压力平衡。在这个实验中，二年级和三年级的学生使用在NASA社区协调建模中心运行的BATS-R-US全球MHD代码的模拟结果来检查磁层顶的位置。学生们还分析了几个航天器的数据，以找到磁层顶交叉。学生们从这个实验室以及接触到空间物理学的工具和技术中获得了他们的结果和模型预测之间的合理一致性。
英文摘要：
Integrating areas of current research into undergraduate physics labs can be a difficult task. The location of the magnetopause is one problem that can be examined with no prior exposure to space physics. The magnetopause location can be viewed as a pressure balance between the dynamic pressure of the solar wind and the magnetic pressure of the magnetosphere. In this lab sophomore and junior students examine the magnetopause location using simulation results from BATS-R-US global MHD code run at NASA's Community Coordinated Modeling Center. Students also analyze data from several spacecraft to find magnetopause crossings. The students get reasonable agreement between their results and model predictions from this lab as well as exposure to the tools and techniques of space physics.
