本文介绍了在太阳风和月球尾流中，利用SELENE（KAGUYA）对月球附近的静电孤立波（ESW）进行的观测。SELENE是一个高度为100公里的月球轨道器，测量波电场、背景磁场、离子和电子通量等。根据不同的观测区域，ESW分为三种类型：由尾流边界中的电场反射和加速的电子产生的ESW（A型），由磁异常上方镜像反射的双流电子产生的强ESW（类型B），以及当局部磁场连接到月球表面时由反射电子产生的ESW（类型C）。C型ESW常与朗缪尔波交替出现。
We present observations of electrostatic solitary waves (ESWs) near the Moon by SELENE (KAGUYA) in the solar wind and in the lunar wake. SELENE is a lunar orbiter with an altitude of 100 km and measured wave electric field, background magnetic field, and fluxes of ions and electrons, etc. ESWs are categorized into three types depending on different regions of observations: ESWs generated by electrons reflected and accelerated by an electric field in the wake boundary (Type A), strong ESWs generated by bi‐streaming electrons mirror‐reflected over the magnetic anomaly (Type B), and ESWs generated by reflected electrons when the local magnetic field is connected to the lunar surface (Type C). ESWs of Type C often alternate with Langmuir waves.
