| 摘 要： | 按恒星演化理论预言,银河系中存在数以亿计的恒星级黑洞.然而,目前已证认的黑洞仅有20个左右.随着天文观测设备的飞跃发展,搜寻黑洞的新方法也陆续被提出.我国大型光学望远镜LAMOST(郭守敬望远镜)的海量恒星光谱让我们可以通过光谱分析来搜寻黑洞.本文回顾了近50年来搜寻恒星级黑洞的历程,介绍了经典的搜寻方法和目前发展的一些新方法,侧重介绍了近期基于LAMOST光谱开展的相关工作,并对未来的搜寻工作给出展望.

| Abstract: | According to the stellar evolution model,108–109 stellar-mass black holes(s MBHs)may exist in the Milky Way.However,only around 20 sMBHs have been dynamically confirmed.With the tremendous advancements in astronomical telescopes,new methods have been proposed to search for s MBHs.A large number of stellar spectra from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope(LAMOST)have enabled us to search for s MBHs through spectral analysis.This article reviews the 50-year history of s MBH search and introduces the classical method and some new methods on this issue.In particular,some recent studies based on LAMOST spectra are presented.Moreover,the prospects of s MBH search are discussed. |
