论文摘要
在本文中，我们研究了一个kazakov-solodukhin黑洞中的光线。为此，我们使用高斯定理内的Kazakov-Solodukhin黑洞的光学几何形状。我们首先显示了变形参数$ a $对高斯光学曲率的效果，然后我们使用Gibbons和Werner普及的现代方法来计算光的弱偏转角。我们对挠度角度的计算表明，重力镜头如何受到变形参数$ a $的影响。此外，我们证明了血浆培养基对Kazakov-Solodukhin黑洞弱重力镜头的影响。我们讨论增加变形参数$ a $，将增加黑洞的弱挠度角。我们的分析还取消了人们如何在偏转角上找到变形参数的观察证据。此外，我们研究了Kazakov-Solodukhin黑洞的严格界限，以解决灰色身体因子，并通过固定$ L = 0 $和$ M = 1 $研究了边界的图形行为，并观察到增加了变形参数$ a $将减少严格的Black book the Black Bool $ t_b $ t_b $ t_b $。
In this paper, we study light rays in a Kazakov-Solodukhin black hole. To this end, we use the optical geometry of the Kazakov-Solodukhin black hole within the Gauss-bonnet theorem. We first show the effect of the deformation parameter $a$ on the Gaussian optical curvature, and then we use the modern method popularized by Gibbons and Werner to calculate the weak deflection angle of light. Our calculations of deflection angle show how gravitational lensing is affected by the deformation parameter $a$. Moreover, we demonstrate the effect of a plasma medium on weak gravitational lensing by the Kazakov-Solodukhin black hole. We discuss that the increasing the deformation parameter $a$, will increase the weak deflection angle of the black hole. Our analysis also uncloak how one may find a observational evidence for a deformation parameter on the deflection angle. In addition, we studied the rigorous bounds of the Kazakov-Solodukhin black hole for the grey body factor and also studied the graphical behaviour of the bounds by fixing $l=0$ and $M=1$ and observed that increasing the deformation parameter $a$ will decrease the rigorous bound $T_b$ of the black hole.
