This work is aimed at the study of traversable wormholes, proposed by Morris and Thorne [Wormholes in spacetime and their use for interstellar travel: A tool for teaching general relativity, Am. J. Phys. 56 (1988) 395], in the framework of f(R,T) = R + αRn + λT gravity, where α, λ and n are constants. The wormhole solutions are obtained and analyzed by using a simplest form of shape function. Further, the existence of photon spheres outside the throat of wormhole due to the gravitational lensing effect is detected.

f(R,T) 重力下的虫洞解，喉部有光子球

这项工作旨在研究由莫里斯和索恩提出的可穿越虫洞[时空中的虫洞及其在星际旅行中的用途：一种教授广义相对论的工具，是。J.物理。 56(1988) 395]，在框架内F(R,吨) = R + αRn + λ吨重力，在哪里α,λ和n是常数。虫洞解是通过使用最简单的形状函数形式获得和分析的。此外，由于引力透镜效应，虫洞喉部外存在光子球。
