摘要
天体物理系统如何将整体运动的动能转化为将粒子加速至极高能量，是一个紧迫的问题。SS 433 是一颗微类星体，发射 TeV 伽马射线，表明存在高能粒子。SS 433 东瓣中一处硬 X 射线发射区最近被确认为一个加速位点。我们用成像 X 射线偏振探测器（Imaging X-ray Polarimetry Explorer）观测了该区域，测得偏振度在 38% 至 77% 之间。若 X 射线源于同步辐射，则高偏振度表明磁场具有良好有序的分量。偏振角在 -12 至 +10 度之间（北偏东），表明磁场平行于喷流。平行于整体流动的磁场亦见于超新星遗迹与强射电星系的喷流中。这可能由流动与周围介质的相互作用引起。
