论文摘要
在本文中，我们主要旨在强调（高）椭圆形积分在强烈引力系统引起的重力效应中的重要性。为此，我们研究了椭圆形积分在光偏转中的应用，因为它通过了浆液介质，周围是带电的Weyl黑洞。为此，我们考虑了两个特定的代数ansatzes，用于等离子折射率，并表征每种情况的光子球。这将进一步用于计算相应黑洞阴影的角直径。我们表明，折射率表达式的复杂性可以导致光行行为对时空参数的显着不同类型。
In this paper, we mainly aim at highlighting the importance of (hyper-)elliptic integrals in the study of gravitational effects caused by strongly gravitating systems. For this, we study the application of elliptic integrals in calculating the light deflection as it passes a plasmic medium, surrounding a charged Weyl black hole. To proceed with this, we consider two specific algebraic ansatzes for the plasmic refractive index, and we characterize the photon sphere for each of the cases. This will be used further to calculate the angular diameter of the corresponding black hole shadow. We show that the complexity of the refractive index expressions, can result in substantially different types of dependencies of the light behavior on the spacetime parameters.
