发布时间：2019-03-26 21:04
【摘要】：简述了精确测定相对自行的方法,特别介绍了在用2～3个历元的底片和CCD观测结果推导恒星自行的过程中如何消除光学视场畸变、星等差和色差的具体办法;并介绍了用星系把相对自行推算绝对自行的方法。还介绍了用自行资料研究银河系结构和演化的一些前沿课题,其中包括星团研究、与银河系兼并的矮星系的发现、暗物质的检测、外星行星的探测和银河系中心黑洞的质量估算等。最后评价了自行在研究银河系中的重要性,论述了我国研制4m光学/近红外望远镜的重要意义。
[Abstract]:This paper briefly describes the method of accurate determination of relative self-motion, especially how to eliminate optical field of view distortion, star magnitude difference and color difference in the process of deducing star motion by using 2 ~ 3 epoch film and CCD observation results. The method of calculating absolute self-propelled by relative self-determination of galaxies is also introduced. It also introduces some cutting-edge topics in the study of the structure and evolution of the Milky way using its own data, including the study of star clusters, the discovery of dwarf galaxies annexed to the Milky way, and the detection of dark matter. Exploration of exoplanets and mass estimation of black holes in the center of the Milky way. Finally, the importance of self-determination in the study of Milky way is evaluated, and the significance of developing 4m optical / near-infrared telescope in China is discussed.
