标题： XMM-Newton EPIC observations of Her X-1

摘要： 我们提供了中子星双星Her X-1的自旋分辨X射线数据。 我们发现6.4 keV的铁线来源于与黑体X射线成分相同的区域。 线条宽度和能量在自旋周期和35天进动周期内发生变化。 我们还发现软X射线和硬X射线光曲线之间的相关性在35天周期内发生变化。 显示英文摘要

摘要： We present spin-resolved X-ray data of the neutron star binary Her X-1. We find evidence that the Iron line at 6.4 keV originates from the same location as the blackbody X-ray component. The line width and energy varies over both the spin period and the 35 day precession period. We also find that the correlation between the soft and hard X-ray light curves varies over the 35 day period.
