【摘要】：简述脉冲星发现和计时观测的概况。文中概述脉冲星计时的物理模型和计算用的各种钦件,特别是全球广泛应用的TEMPO2软件,并描述脉冲星计时阵的概念和国际脉冲星计时阵。对脉冲星计时观测应用:建立脉冲星时标、改进行星历表(包括外行星质量测定和海外天体的发现)、检测引力波、测定脉冲星的旋转和天体测量参数、脉冲星自主导航、相对论引力理论的验证等作了介绍。最后,对我国开展此项工作的情况给予简要描述,并提出若干建议。
[Abstract]:The general situation of pulsar discovery and timing observation is briefly described. In this paper, the physical model of pulsar timing and all kinds of prefixes for calculation, especially the TEMPO2 software widely used in the world, are summarized. The concept of pulsar timing array and the international pulsar timing array are described. Pulsar timing observation applications: establishing pulsar time scales, changing ephemeris (including mass measurements of outer planets and discoveries of overseas celestial bodies), detecting gravitational waves, measuring pulsar rotation and astrometric parameters, pulsar autonomous navigation, The verification of the theory of relativistic gravity is introduced. Finally, the paper gives a brief description of the work in China, and puts forward some suggestions.
