虫洞状静态以太溶液的阴影
Shadow of the wormholelike static aether solution
摘要：
最近，在各向同性坐标系中，爱因斯坦-以太理论的解析解被明确地给出。其特征在于质量参数$m$和组合耦合常数$c_{14}$。通过坐标变换，证明了该解与已知的静态以太解是等价的。假设光子与以太和引力的耦合最小，我们通过改变$c_{14}$来研究光子球和解的阴影。并与Schwarzschild黑洞的结果进行了比较。
英文摘要：
Recently, an analytical solution in Einstein-aether theory was presented explicitly in isotropic coordinates. It is characterized by a mass parameter $m$ and a combined coupling constant $c_{14}$. By a coordinate transformation, we verify this solution is equivalent to the previously known static aether solution. Assuming photons couple minimally to aether and gravity, we investigate the photon sphere and shadow of the solution by varying $c_{14}$. Results are compared with those of the Schwarzschild black hole.
