摘要
本文描述了偏振光谱望远镜阵列(PolSTAR)，这是一项向NASA 2014年小型探测器(SMEX)机会公告提议的任务。PolSTAR测量3-50 keV（要求；目标：2.5-70 keV）X射线的线偏振，探测在黑洞事件视界附近的极端条件下以及磁星和中子星内部与周围的物质、辐射和时空结构的行为。PolSTAR的设计基于为2012年6月发射的核光谱望远镜阵列(NuSTAR)任务开发的技术。具体而言，它使用与NuSTAR相同的X射线光学系统、可展开望远镜桅杆、光学平台以及CdZnTe探测器。该任务具有测量流量低至~5 mCrab的X射线源~1%线偏振分数的灵敏度。本文描述了PolSTAR设计以及科学驱动因素和潜在科学回报。
