论文摘要
在本文中，我们讨论了在黑色孔孔的背景下的弱重力镜头。最初，我们通过带电的丝状黑洞检查光子的挠度角。为了这种愿望，我们计算高斯光学曲率并实现高斯式定理，以研究弦黑孔的球形平衡时空的挠度角。我们还分析了弱重力透镜中血浆介质的影响。此外，在等离子体和非血浆介质中研究了冲击参数$ b $，Black Hole Charge $ Q $对挠度角度的偏转角度的图形影响。
In this paper, we discuss the weak gravitational lensing in the context of stringy black holes. Initially, we examine the deflection angle of photon by charged stringy black hole. For this desire, we compute the Gaussian optical curvature and implement the Gauss-Bonnet theorem to investigate the deflection angle for spherically balanced spacetime of stringy black hole. We also analyze the influence of plasma medium in the weak gravitational lensing for stringy black hole. Moreover, the graphical impact of impact parameter $b$ , black hole charge $Q$ on deflection angle by charged stringy black hole has been studied in plasma as well as non-plasma medium.
