摘要:

本工作探索了绕扭曲变形致密天体运行的测试粒子的动力学特性。选择此类背景的天体物理动机是构建更合理的真实情况模型,该情况出现在致密天体附近,且可能存在作为额外物理自由度的参数,这有助于将观测数据与天体物理系统关联。本工作的主要目标是研究该背景下依赖系统不同参数的运动动力学状态和准周期振荡,同时我们验证了径向与垂直振荡在观测到的3:2准周期振荡频率比下的共振现象。

英文摘要:

This work explores the dynamic properties of test particles surrounding a distorted, deformed compact object. The astrophysical motivation was to choose such background, which could constitute a more reasonable model of a real situation that arises in the vicinity of compact objects with the possibility of having parameters as the extra physical degrees of freedom. This can facilitate associating observational data with astrophysical systems. This work's main goal is to study the dynamic regime of motion and quasi-periodic oscillation in this background, depending on different parameters of the system. Also, we exercise the resonant phenomena of the radial and vertical oscillations at their observed quasi-periodic oscillations frequency ratio of 3:2.
