论文摘要
在本文中，我们研究了标量张量矢量重力（STVG）中静态球形对称解的存在，并研究了其地平线距离以开发我们的测试粒子的边界限制。我们已经计算了该度量标准的Kretschmann不变性，以研究奇异性，并验证它是否将其减少为一般相对论的Kretschmann不变为$α\ rightarrow0 $。此外，我们通过开发有效的电势和最内向的稳定圆形轨道（ISCO）的半径，研究了静态溶液周围时间样和光明测试粒子的轨道运动。
In this article, we have examined the existence of a static spherically symmetric solution in the Scalar Tensor Vector Gravity (STVG) and investigated its horizon distances to develop boundary limitations for our test particle. We have computed the Kretschmann invariant of the metric to study the singularities and verify that it reduces to general relativity's Kretschmann invariant as $α\rightarrow0$. Further, we investigated the orbital motion of a time-like and light-like test particle around the static solution by developing an effective potential and the radius of the innermost stable circular orbit (ISCO).
