中子星和黑洞中的高频QPO:探测致密物质和强引力场

High Frequency QPOs in Neutron Stars and Black Holes: Probing Dense Matter and Strong Gravitational Fields

Frederick K. Lamb

摘要:

在许多中子星和黑洞的X射线辐射中发现了准周期振荡。频率大于300赫兹的QPO被认为产生于中子星表面和黑洞的事件视界附近。首先总结了中子星和黑洞系统中QPO的一些重要性质。然后,我回顾了一些已经提出的模型,并将它们与观测数据进行比较。最后,我描述了这些QPO如何可以用来确定致密物质和强引力场的性质。

英文摘要:

Quasi-periodic oscillations (QPOs) have been discovered in the X-ray emission of many neutron stars and black holes. The QPOs with frequencies greater than about 300 Hz are thought to be produced near the surfaces of neutron stars and the event horizons of black holes. I first summarize some of the most important properties of the QPOs seen in neutron star and black hole systems. I then review some of the models that have been proposed and compare them with observational data. Finally, I describe how these QPOs can be used to determine the properties of dense matter and strong gravitational fields.
