作为电子尺度电流片中抗磁漂移表现的电子新月分布
Electron crescent distributions as a manifestation of diamagnetic drift in an electron scale current sheet
摘要：
我们报告磁层多尺度观测电子压力梯度电场附近的磁重联扩散区使用一种新的技术提取7.5毫秒的电子矩的快速等离子体调查。我们发现，在离面电流密度增加的区间内，垂直电子体速度与$E \times B$漂移的偏离可以用抗磁漂移来解释。在面外电流过渡到面内电流的间隔中，电子动量方程在7.5 ms分辨率下不满足。
英文摘要：
We report Magnetospheric Multiscale observations of electron pressure gradient electric fields near a magnetic reconnection diffusion region using a new technique for extracting 7.5 ms electron moments from the Fast Plasma Investigation. We find that the deviation of the perpendicular electron bulk velocity from $E \times B$ drift in the interval where the out-of-plane current density is increasing can be explained by the diamagnetic drift. In the interval where the out-of-plane current is transitioning to in-plane current, the electron momentum equation is not satisfied at 7.5 ms resolution.
