摘要:

本文计算了平面和极球光子绕旋转黑洞的轨道半径的解析解,该黑洞与经典场和弦云有关。这包括一个完整的分析治疗的五次,描述轨道上的赤道平面。进一步研究了碰撞参量的径向分布,导出了极限情况下的半径。对于更一般的情况,我们也讨论了光子区域,形成这个黑洞。为了模拟出现在不同倾角的轨道,我们解析地解决纬向和方位角的运动方程的Weierstrassian椭圆函数,考虑的半径的球形轨道,在其一般形式,作为初始条件。给出了轨道的周期和稳定性条件。

英文摘要:

In this paper, we calculate the analytical solutions for the radii of planar and polar spherical photon orbits around a rotating black hole that is associated with quintessential field and cloud of strings. This includes a full analytical treatment of a quintic that describes orbits on the equatorial plane. Furthermore, The radial profile of the impact parameters is studied and the radii corresponding to the extreme cases are derived. For the more general cases, we also discuss the photon regions that form around this black hole. To simulate the orbits that appear in different inclinations, we analytically solve the latitudinal and azimuth equations of motion in terms of the Weierstrassian elliptic functions, by considering the radii of spherical orbits, in their general form, as the initial conditions. The period and the stability conditions of the orbits are also obtained analytically.
