论文摘要
我们认为，使用最近启动的成像X射线极化勘探器对X射线极化的测量将回答许多有关磁铁的开放性问题，尤其是其表面的物理状态，是否存在真空双折射，以及这些对象的硬X射线发射的性质。我们概述了仪器的功能，特定模型以及磁铁4U〜0142+61的模拟结果。
We argue that measurements of X-ray polarization using the recently launched Imaging X-ray Polarimetry Explorer will answer many open questions about magnetars in particular the physical state of their surfaces, whether vacuum birefringence exists, and the nature of the hard X-ray emission from these objects. We outline the capabilities of the instrument, specific models and the results of simulations for the magnetar 4U~0142+61.
