摘要
综述了有关Ｘ射线脉冲星的基本观测事实及最新进展，涉及双星、中子星及强磁场等方面的观测证据，并介绍了中子星及其伴星质量的测定。一般认为，Ｘ射线脉冲产生于年轻的大质量Ｘ射线双星（ＨＭＸＢ）中，而Ｘ射线爆发则起源于小质量Ｘ射线双星（ＬＭＸＢ）中。然而，１９９５年１２月２日Ｃｏｍｐｔｏｎγ射线天文台（ＣＧＲＯ）发现的ＧＲＯＪ１７４４－２８却是既有Ｘ射线脉冲，又有Ｘ射线爆发。本文对这一发现做了简要的介绍。
The basic observations of the Xray pulsars have been reviewed,including the binary star systems,the strong magnetic fields of neutron stars,the determination of the masses of neutron star and its company,etc.Usually,the Xray pulsars have been found in the High Mass Xray Binaries(HMXB),and the Xray bursts have been found in the Low Mass Xray Binaries(LMXB).However,as an Xray pulsar,GRO J174428,discovered by the Compton γ ray Observatory in the December 2(1995),acts also as an Xray burster.This new discovery has been introduced in this paper.
