论文摘要
本文研究了相对论，非自我磨碎的托里在变形的变形物体背景下的振荡特性。这项工作集中在静态和轴向对称度量上，其中包含两个四极参数。与中心对象和外部字段有关。该指标可以将可观察的效应与这些参数相关联，以作为动态的自由度。选择这样一个领域的天体物理动机是为紧凑物体附近发生的实际情况构成合理模型的可能性。本文旨在通过局部分析研究完美的流体磁盘中的径向上环状频率，而不是测试粒子的情况。为了实现这一目标，我们采用垂直集成的技术来分析方程。 Tori还以特定角动量的开普勒和非忽视分布进行建模，我们讨论了振荡性能对与角动量分布和四倍体相关的模型变量的依赖性。在目前的贡献中，我们进一步探索了这些特性，其可能性将振荡频率与某些高频准周期振荡模型和观察到的数据联系起来。
This paper studies the oscillation properties of relativistic, non-self-gravitating tori in the background of a distorted deformed compact object. This work concentrates on the static and axially symmetric metric containing two quadrupole parameters; relating to the central object and the external fields. This metric may associate the observable effects to these parameters as dynamical degrees of freedom. The astrophysical motivation for choosing such a field is the possibility of constituting a reasonable model for an actual scenario occurring in the vicinity of compact objects. This paper aims to investigate the radial epicyclic frequency in a perfect fluid disk and not a test particle scenario via a local analysis. To achieve this goal, we employ the vertically integrated technique to able to treat the equation analytically. The tori are also modelled with Keplerian and non-Keplerian distributions of specific angular momentum, and we discuss the dependence of oscillation properties on the variable of the model related to angular momentum distribution and quadrupoles. In the present contribution, we further explore these properties with the possibility of relating oscillatory frequencies to some high-frequency quasi-periodic oscillations models and observed data.
