绕黑洞圆盘的翘曲和偏心传播
Warp and eccentricity propagation in discs around black holes
摘要：
我们考虑了在各种条件下围绕黑洞的圆盘中翘曲和偏心扰动的向内传播。在我们的计算中，我们使用长期理论的翘曲和偏心盘，并假设变形是固定的，并在一个类似的区域（a）和（b）的Shakura和Sunyaev盘的盘模型中传播。我们发现，传播的变形的最里面的区域的光盘是有利于低粘性阻尼和高吸积率。我们将我们的结果与可能激发的被困惯性模式，并在黑洞系统中的甚高谱态的高频准周期振荡（QPO）的观察。
英文摘要：
We consider the inward propagation of warping and eccentric disturbances in discs around black holes under a wide variety of conditions. In our calculations we use secular theories of warped and eccentric discs and assume the deformations to be stationary and propagating in a disc model similar to regions (a) and (b) of Shakura and Sunyaev discs. We find that the propagation of deformations to the innermost regions of the disc is facilitated for low viscous damping and high accretion rate. We relate our results to the possible excitation of trapped inertial modes, and to the observations of high-frequency quasi-periodic oscillations (QPOs) in black hole systems in the very high spectral state.
