摘要:

我们研究了天体物理黑洞的自旋角动量在控制后牛顿伪克尔黑洞势的影响下运动的测试粒子的特殊相对论混沌动力学中的作用,以及由不对称放置的(偶极)晕产生的微扰势。提出了一个类李雅普诺夫指数作为衡量系统混沌程度的有效尺度,发现黑洞自旋与上述动力学的混沌程度反相关.我们的研究结果已经解释了应用动力系统分析的一般原则。

英文摘要:

We investigate the role of the spin angular momentum of astrophysical black holes in controlling the special relativistic chaotic dynamics of test particles moving under the influence of a post-Newtonian pseudo-Kerr black hole potential, along with a perturbative potential created by a asymmetrically placed (dipolar) halo. Proposing a Lyapunov-like exponent to be the effective measure of the degree of chaos observed in the system under consideration, it has been found that black hole spin anti-correlates with the degree of chaos for the aforementioned dynamics. Our findings have been explained applying the general principles of dynamical systems analysis.
