论文摘要
B Black Hole X射线二进制文件中隐约了解了B QPO与内积盘区域中热流的连接。我们对二十三个观察结果进行了光谱和定时研究，其中发生了类似质心频率（〜6 Hz）的型C型和B型QPO。它们的频谱差异用于了解B型QPO的生产机理以及准简单无线电观察结果。基于光谱结果，我们没有注意到Comptonization参数和类型-B QPO期间的内部磁盘半径的许多变化。我们发现，基于COMPTT模型与类型-C和类型B QPO相关的观察结果必须不同。发现无线电通量密度与QPO宽度，柔软的硬通量比和QPO宽度与内磁盘温度，遵循某些趋势，这表明射流可以负责H1743-322中的B型B QPO。需要进一步的研究以唯一限制这种情况。在一项案例研究中，注意到从C型到B型QPO的逐渐过渡，我们发现光谱变化可以通过射流或垂直扩展的光学较厚的组合区域来解释。纳入了内部区域中具有热流和射流的几何晶状体裂解模型，以解释光谱和时机变化。
The connection of type-B QPOs to the hot flow in the inner accretion disk region is vaguely understood in black hole X-ray binaries. We performed spectral and timing studies of twenty-three observations where type-C and type-B QPOs with similar centroid frequencies (~ 6 Hz) occurred. Their spectral differences were used to understand the production mechanism of type-B QPOs, along with the quasi-simultaneous radio observations. Based on the spectral results, we did not notice many variations in the Comptonization parameters and the inner disk radius during type-C and type-B QPOs. We found that the structure of the Comptonization region has to be different for observations associated with type-C and type-B QPOs based on the CompTT model. Radio flux density vs QPO width, soft to hard flux ratio, and QPO width vs inner disk temperature, were found to follow certain trends, suggesting that a jet could be responsible for the type-B QPOs in H1743-322. Further studies are required to uniquely constrain this scenario. In a case study where a gradual transition from type-C to type-B QPO was noticed, we found that the spectral changes could be explained by the presence of a jet or a vertically extended optically thick Comptonization region. The geometrical Lense-Thirring precession model with a hot flow and a jet in the inner region was incorporated to explain the spectral and timing variations.
