核动力X射线毫秒谱仪

Nuclear-powered X-ray millisecond pulsars

Sudip Bhattacharyya

摘要:

核动力X射线毫秒级中子星是第三种毫秒级中子星,由热核聚变过程提供动力。在某些热核X射线爆发期间,当燃烧和冷却的吸积物质在旋转的中子星表面上产生方位角不对称的亮度图案时,观察到相应的亮度振荡,称为爆发振荡。除了提供中子星的自旋速率外,这种X射线定时特征可以成为探测中子星内部和表面基本物理的有用工具。本章概述了相对较新的核动力X射线毫秒谱仪领域。

英文摘要:

Nuclear-powered X-ray millisecond pulsars are the third type of millisecond pulsars, which are powered by thermonuclear fusion processes. The corresponding brightness oscillations, known as burst oscillations, are observed during some thermonuclear X-ray bursts, when the burning and cooling accreted matter gives rise to an azimuthally asymmetric brightness pattern on the surface of the spinning neutron star. Apart from providing neutron star spin rates, this X-ray timing feature can be a useful tool to probe the fundamental physics of neutron star interior and surface. This chapter presents an overview of the relatively new field of nuclear-powered X-ray millisecond pulsars.
