摘要

磁层顶在太阳风、磁鞘和磁层之间的耦合中起着关键作用。通过使用 MMS 分析穿越磁层顶事件，我们揭示了磁层顶边界层和相关电场中电荷的局部非中性。电场结构分为两类。一类通常发生在黄昏一侧，电场指向地球。另一类通常出现在白天，电场指向远离地球的方向。这种电场非中性的空间范围约为 600 公里，与离子回旋运动的尺度相当。这些发现为了解磁层顶的精细结构以及磁鞘和磁层之间的耦合提供了宝贵的见解。

The Electric Properties of the Magnetopause Boundary Layer

The magnetopause plays a pivotal role in the coupling among solar wind, the magnetosheath, and the magnetosphere. By analyzing magnetopause crossing events using MMS, we reveal a local non-neutrality of electric charges in the magnetopause boundary layer and the associated electric field. There are two types of electric structures. In one group, which typically occurs on the dusk side, the electric field directs towards the Earth. In the other, which generally occurs on the day side, the field directs away from the Earth. The spatial extent of this electric non-neutrality spans approximately 600 km, which is at the scale of ion gyrational motion. These findings provide valuable insights into the fine structures of the magnetopause and the coupling between the magnetosheath and the magnetosphere.

期刊介绍： Magnetochemistry (ISSN 2312-7481) is a unique international, scientific open access journal on molecular magnetism, the relationship between chemical structure and magnetism and magnetic materials. Magnetochemistry publishes research articles, short communications and reviews. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced.
