帕克太阳探测器是第一个原位探测日光层最内层的任务，揭示了异常动态和结构化的外日冕。其有效负载包括一个搜索线圈磁力计 (SCM)，可测量 3 Hz 至 1 MHz 之间波动磁场的三个分量。经过三年多的运行，SCM 揭示了太阳风中多种不同的波动现象。在这里，我们概述了迄今为止的一些发现。其中包括斜向和向阳传播的哨声波，这对于它们与高能电子的相互作用非常重要，首次观察到与尘埃撞击期间逃逸电子相关的磁特征，首次观察到III型无线电爆发事件期间慢异常波模式的磁场分量，等等。本研究重点关注迄今为止的主要观察结果，包括仪器的描述和经验教训。
Parker Solar Probe is the first mission to probe in situ the innermost heliosphere, revealing an exceptionally dynamic and structured outer solar corona. Its payload includes a search‐coil magnetometer (SCM) that measures up to three components of the fluctuating magnetic field between 3 Hz and 1 MHz. After more than 3 years of operation, the SCM has revealed a multitude of different wave phenomena in the solar wind. Here we present an overview of some of the discoveries made so far. These include oblique and sunward propagating whistler waves that are important for their interaction with energetic electrons, the first observation of the magnetic signature associated with escaping electrons during dust impacts, the first observation of the magnetic field component for slow extraordinary wave modes during type III radio burst events, and more. This study focuses on the major observations to date, including a description of the instrument and lessons learned.
