We present Magnetospheric Multiscale observations showing large numbers of slow electron holes with speeds clustered near the local minimum of double-humped velocity distribution functions of background ions. Theoretical computations show that slow electron holes can avoid the acceleration that otherwise prevents their remaining slow only under these same circumstances. Although the origin of the slow electron holes is still elusive, the agreement between observation and theory about the conditions for their existence is remarkable.

慢电子空穴的航天器观测和理论理解

我们展示了磁层多尺度观测,显示了大量慢电子空穴,其速度聚集在背景离子双峰速度分布函数的局部最小值附近。理论计算表明,只有在这些相同的情况下,慢电子空穴才能避免加速,否则会阻止它们保持缓慢。尽管慢电子空穴的起源仍然难以捉摸,但观察和理论之间关于它们存在条件的一致性是显着的。
