黑洞双星的X射线辐射

X-ray emission from black-hole binaries

M. Gilfanov

摘要:

综述了吸积黑洞的X射线发射特性。在致密天体附近的吸积和X射线辐射的形成的当代观测图像和理论认识的现状同样是本章的重点。重点主要放在共同的属性和趋势,而不是个别对象的特殊性和特定理论模型的细节。本章首先讨论了吸积流的几何结构、X射线发射谱分量和黑洞谱态。着重介绍了X射线偏振测量技术的应用前景和诊断潜力。重点讨论了X射线发射的一般变化和不同光谱成分的变化--吸积盘的发射、康普顿化辐射和反射成分。本文回顾了X射线发射的光谱特性和时间特性之间的关系,并在理论模型的范围内进行了讨论。最后,与吸积中子星作了比较。

英文摘要:

The properties of X-ray emission from accreting black holes are reviewed. The contemporary observational picture and current status of theoretical understanding of accretion and formation of X-ray radiation in the vicinity of the compact object are equally in the focus of this chapter. The emphasis is made primarily on common properties and trends rather than on peculiarities of individual objects and details of particular theoretical models. The chapter starts with discussion of the geometry of the accretion flow, spectral components in X-ray emission and black hole spectral states. The prospects and diagnostic potential of X-ray polarimetry are emphasized. Significant attention is paid to the discussion of variability of X-ray emission in general and of different spectral components -- emission of the accretion disk, Comptonized radiation and reflected component. Correlations between spectral and timing characteristics of X-ray emission are reviewed and discussed in the context of theoretical models. Finally, a comparison with accreting neutron stars is made.
