發(fā)布時間:2018-11-02 16:09
【摘要】:簡述脈沖星發(fā)現(xiàn)和計時觀測的概況。文中概述脈沖星計時的物理模型和計算用的各種欽件,特別是全球廣泛應用的TEMPO2軟件,并描述脈沖星計時陣的概念和國際脈沖星計時陣。對脈沖星計時觀測應用:建立脈沖星時標、改進行星歷表(包括外行星質量測定和海外天體的發(fā)現(xiàn))、檢測引力波、測定脈沖星的旋轉和天體測量參數(shù)、脈沖星自主導航、相對論引力理論的驗證等作了介紹。最后,對我國開展此項工作的情況給予簡要描述,并提出若干建議。
[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.
