这是第一次，在太阳风中的湍流磁场波动的色散关系直接确定的顺序的电子惯性长度的小尺度上，使用四点磁强计观测磁层多尺度使命。使用高分辨率自适应波望远镜技术的数据进行了分析。小尺度太阳风湍流主要由高度倾斜传播的波组成，其色散与哨声模式的色散一致。
For the first time, the dispersion relation for turbulence magnetic field fluctuations in the solar wind is determined directly on small scales of the order of the electron inertial length, using four-point magnetometer observations from the Magnetospheric Multiscale mission. The data are analyzed using the high-resolution adaptive wave telescope technique. Small-scale solar wind turbulence is primarily composed of highly obliquely propagating waves, with dispersion consistent with that of the whistler mode.
