蜘蛛脉冲星掩食现象的研究进展

The Research Progress of the Eclipsing Phenomenon of Spider Pulsars

蜘蛛脉冲星的发现是研究毫秒脉冲星演化的重要进展,它们被认为可能是孤立毫秒脉冲星的来源之一。蜘蛛脉冲星系统含有丰富的观测现象,其中最重要的就是脉冲星的掩食。掩食脉冲星的研究可以帮助理解脉冲双星的演化、球状星团的形成和星际介质等。介绍了近年来脉冲星掩食研究的主要进展,包括脉冲星的掩食特点,掩食脉冲星系统的统计和举例,并阐述了常用的掩食机制。在未来10年里,随着超高灵敏度和超快巡天速度的射电望远镜的投入使用,如平方公里阵列射电望远镜(Square Kilometre Array,SKA)等,掩食脉冲星的研究有望打开新局面,并对掩食机制理论的发展产生积极的影响,帮助解决一些未解之谜。

The discovery of spider pulsars is an important progress in the study of the formation and evolution of millisecond pulsars,since they are considered to be one of the origins of isolated millisecond pulsars.The spider pulsar systems are rich in observational phenomena,and the most important of them is the eclipse of the pulsar.The study of eclipsing pulsars can help to understand the evolution of binary pulsars,the formation of globular clusters and the interstellar medium.Since the first eclipsing pulsar discovered in 1988,over 60 eclipsing pulsars have been discovered in the past three decades.Here shows the main progress of research on eclipsing pulsars in recent years,including the eclipsing characteristics,statistics and examples of known eclipsed pulsar systems,and explain the most common eclipsing mechanisms.In the next ten years,with the use of radio telescopes with ultra high sensitivity and sky survey speed,such as the Square Kilometre Array Radio Telescope(SKA),the research on eclipsing pulsar is expected to open up new horizons and have positive influences on the development of the theory of eclipsing mechanisms,and help to solve some of these unsolved eclipsing mysteries.
