估算有中子星作伴星的黑洞质量

在本文中，我们讨论了由中子星和黑洞构成的密近双星系统的引力效应。首先，我们清楚地解释了引力辐射存在引起的轨道圆化，并估算了圆化的时间尺度。求解了围绕史瓦西黑洞作圆轨道运动的矢量进动方程，得到了一个精确解。由进动周期和中心黑洞的质量的关系，我们得到了估算中子星伴随的黑洞质量的方法。随后我们讨论了以中子星脉冲信号随自旋进动变化来寻找黑洞的方法。

Mass Estimation of Blackhoie Companied With a Neutron Star

A gravitational effect of binary system composed of a close neutron star and a blackhole has been discussed in this paper. The orbit circulization caused by gravitation radiation has been Explained clearly and a time scale of the orbit circuliztion is also estimated. We have solved the vector equation of the procession in a circular orbit round a shwarchild blackhole, and a exact solution of the equation has been obtained. Based on a relationship between the precession period and the mass of the central blackhole, a method of estimating the mass of blackhole companied with a neutron star is found by Us. It allows us to discuss a way of discovering blackholes. As a conclusion, we have discussed the way of discovering blackholes by means of the pulse variations of their neutron stars versus spin procession.
