论文摘要
在本文中，我们研究了静态和球形对称的Bardeen-kiselev黑洞（BK BH）周围的粒子动力学，这是Einstein-Non-linear-linear Maxwell场方程的解决方案以及典型场。我们讨论其必不可少的几何特性，例如标量不变性和最内向稳定的圆形轨道的大小。还研究了BH周围测试颗粒的动力学。此外，我们还计算了在略微扰动轨道中绕BH绕的测试粒子的基本频率。 Further, the degeneracy relations between the spin of rotating Kerr BH and magnetic charge of the BK BH at the values of the quintessential parameter $ω_q=-1/3$ and in terms of the same values of innermost stable circular orbits (ISCOs) radius, energy efficiency, twin-peaks quasiperiodic oscillations (QPOs) frequencies and impact parameter for photon are also discussed in detail.最后，我们研究了阴影半径与准模式（QNM）频率的实际部分之间的关系。
In this article, we study the particle dynamics around a static and spherically symmetric Bardeen-Kiselev black hole (BK BH) which is a solution of the Einstein-non-linear Maxwell field equations along with a quintessential field. We discuss its essential geometrical properties such as scalar invariants and size of innermost stable circular orbits. Dynamics of test particles around the BH is also studied. Moreover, we also computed the fundamental frequencies of a test particle orbiting the BH in a slightly perturbed orbit. Further, the degeneracy relations between the spin of rotating Kerr BH and magnetic charge of the BK BH at the values of the quintessential parameter $ω_q=-1/3$ and in terms of the same values of innermost stable circular orbits (ISCOs) radius, energy efficiency, twin-peaks quasiperiodic oscillations (QPOs) frequencies and impact parameter for photon are also discussed in detail. Finally, we have investigated the relationship between the shadow radius and the real part of the quasinormal mode (QNM) frequency.
