论文摘要
我们考虑了一个黑洞的简单模型，该模型被环形结构包围，并由于磁场和潮汐力而经历了变形。对于此系统，我们构建了Preston-Poisson Black Hole的阴影，将其应用于超大的黑洞$ M87^*$，并将其与相应的Schwarzschild和Kerr黑洞的阴影进行比较。我们发现，对于大偏差参数$ b $和$ e $，Preston-Poisson黑洞的阴影显然可以与Kerr Black Hole区分开。
We consider a simple model of a black hole surrounded by a toroidal structure and experiencing deformation due to magnetic field and the tidal force. For this system we construct the shadows of Preston-Poisson black hole, apply it to supermassive black hole $M87^*$ and compare it with the shadows of corresponding Schwarzschild and Kerr black holes. We find that for large deviation parameters $B$ and $E$ the shadow of Preston-Poisson black hole is clearly distinguishable from Kerr black hole provided the angular resolution of measurements is of order $μ\mathrm{arcsec}$.
