摘要
随着对外太空探索脚步的加快,人类开始对与太阳系具有相似结构的恒星行星系统越来越感兴趣,因为它们有可能也拥有智慧生命。简单介绍了目前地外恒星行星系统的探测情况,分析了现在比较常用的几种探测方法的可行性和适用范围,重点讨论了利用视向速度法得到的结果及其意义。近年来,各种探索地外行星的小卫星的升空以及探测技术的进步使得大批高质量数据获得成为可能。可以预见,在未来几年内,地外恒星行星系统的探索将会进入一个蓬勃发展阶段。
With the advance of the space exploring, the study of the extra-solar planetary systems becomes an interesting topic since such system may exist the life or even the modern civilization. In this paper we give a brief introduction on the discovery of extra-solar planetary systems, and discuss the feasibility of detection techniques and methods developed in recent years. In particular, we present detailed interpretations of the results by the radial velocity method. With the launch of some specific small satellites, we can predict the discovery of a large number of candidates of the extra-solar planetary systems. We can expect that the exploring of extra-solar planetary systems will have a prospective era in the near future.
