Clarification of electromagneticenvironmentaround Moon by KAGUYA

月亮女神月球轨道器上的低频波接收器观测到各种波。由于太阳风和月球之间的相互作用，不仅观测到宽带静电噪声（BENs），而且还观测到自Geotail卫星发现以来非常感兴趣的静电孤立波（ESWs）。利用等离子体和磁场数据导出了电子速度分布函数，该函数有助于澄清月球周围的电磁环境和理解波粒相互作用。

Low-frequency wave receiver on-board the KAGUYA lunar orbiter observed various waves. As a result of the interaction between the solar wind and Moon, not only the broad-band electrostatic noise (BENs) are observed, but electrostatic solitary waves (ESWs) which are very interested since they were discovered the Geotail satellite are also observed by the waveform capture. The electron velocity distribution functions, which are useful to clarify electromagnetic environment around Moon and understand the wave-particle interaction, are derived from plasma and magnetic field data.
