摘要
LISA Pathfinder (LPF) 是一项基于空间的任务，旨在测试未来空间引力波天文台所需的新技术。磁驱动力在低频段（mHz 及以下，即空间天文台感兴趣的测量频带）的仪器灵敏度中起着关键作用。磁场可与测试质量的磁化率和剩余磁矩耦合，并使其偏离测地线运动。LISA Pathfinder 搭载了一个专用的磁测量子系统，从 1 Hz 到 1 mHz 噪声水平为 10 。在本文中，我们报告了 LISA Pathfinder 运行期间的磁测量情况。我们表征了航天器内的磁环境，研究了磁场的时间演化及其低至 20 Hz 的稳定性，在此处我们测得约 200 的值，并识别出两种不同的频率 regime，一种与行星际磁场相关，另一种与航天器内部产生的磁场相关。最后，我们表征了 mHz 以下磁场波动的非平稳分量，并将其与太阳风动力学联系起来。
