摘要
本文对最近(1989年1月)在大麦哲伦云中著名超新星SNl987A内发现的一颗亚毫秒周期的光学脉冲星及其引起的研究热潮作了比较系统的评述。首先比较详细地给出了这颗脉冲星的基本观测事实和数据,然后分析了两类可能的理论模型——自转模型和振荡模型。也讨论了这颗脉冲星究竟是不是在这次超新星爆发时产生的问题。并且还讨论了这颗脉冲星对中子星物态所能给出的信息,以及它的γ射线光度的理论估计。
In this paper, the present status of the researches on PSR 0636-69 are reviewed. First, the basic observational facts and data about this pulsar are given in detail. Then, two kinds of possible theoretical models, namely the rotating and the vibrating neutron star models, are analysed. And furthermore, some interesting problems related with the rotating neutron star model, such as the possibility of PSR 0635-69 being an old pulsar, the limitations on possible equations of state of this neutron star, and others, are also discussed.
