论文摘要
本文旨在研究在克鲁格洛夫（Kruglov）提出的非线性电动力学模型中获得的电气和磁性黑洞溶液的天体物理适用性（Ann。Phys。Berlin2017，529，170073）。通过使用带电的紧凑型物体的出色数据和假设的Quark Star模型来研究弯曲角度和重力红移的理论计算。计算表明，尽管理论结果与线性麦克斯韦的情况有所不同，但绘制的弯曲角与线性情况一致，并且很难识别非线性的效果。然而，红移的计算表明，尽管电场的增加导致重力红移的减少，但强磁场的存在会越来越多地导致重力红移。
This paper aims to investigate the astrophysical applicability of the electrically and magnetically charged black hole solutions obtained in a model of nonlinear electrodynamics proposed by Kruglov (Ann. Phys. Berlin 2017, 529, 170073). Theoretical calculations of the bending angles and gravitational redshifts from the theory of general relativity are studied numerically by using the stellar data of charged compact objects and a hypothetical quark star model. Calculations have revealed that although the theoretical outcomes differ from the linear Maxwell case, the plotted bending angles coincide with the linear case and it becomes hard to identify the effect of nonlinearity. However, the calculation of the redshift has shown that while the increase in the electric field leads to a decrease in the gravitational redshift,the presence of the strong magnetic field contributes to the gravitational redshift in an increasing manner.
