论文摘要
银河黑洞二进制文件的X射线光谱是获得对系统的整体理解的强大工具。不仅可以详细研究积聚磁盘的性能，还可以推断出黑洞的基本特性。对这些目标的追求也会导致在强场上限制中对一般相对性的间接验证。在这项工作中，我们使用来自MITER和NUSTAR观测值的数据对银河X射线二进制二进制Maxi J1631-479进行了全面的光谱分析。我们追踪积聚磁盘特性的演变，例如密度，电离，Fe丰度等，因为源从磁盘的源过渡主导了软状态，以势力为主导的硬性中间状态。我们对黑洞的自旋和内盘的倾斜度提供了强大的约束。我们还使用较好的观测来使用柔软的状态来使用光学观测的距离估计来限制黑洞质量。
X-ray spectroscopy of galactic black hole binaries serve as a powerful tool to gain an overall understanding of the system. Not only can the properties of the accretion disk be studied in detail, the fundamental properties of the black hole can also be inferred. The pursuit of these objectives also leads to an indirect validation of general relativity in strong field limit. In this work we carry out a comprehensive spectral analysis of the galactic X-ray binary MAXI J1631-479 using data from NICER and NuSTAR observatories. We trace the evolution of the accretion disk properties such as density, ionization, Fe abundance, etc as the source transitions from a disk dominated soft state to a power law dominated hard intermediate state. We provide strong constrains on the spin of the black hole and the inclination of the inner disk. We also use the soft state NICER observations to constrain the black hole mass using distance estimates from optical observations.
