关于HZ Her/Her X-1中35天周期的性质
On the nature of the 35-day cycle in HZ Her/Her X-1
摘要：
本文研究了Her X-1脉冲周期随Fermi-GBM观测到的X射线通量的规律性变化。我们认为，这些有规律的变化是由于中子星在Her X-1的自由进动。
英文摘要：
Regular variations of the pulse period of Her X-1 with X-ray flux observed by Fermi-GBM are examined. We argue that these regular variations result from the free precession of the neutron star in Her X-1.
