论文摘要
在爱因斯坦 - æther理论中，洛伦兹对称性在高能状态下由于田地的存在而被局部损坏。这将在天文观察上留下重大烙印。在本文中，我们研究了爱因斯坦-æther理论中两种类型的静态和球形对称黑洞的光学外观。通过Euler-Lagrange方程，我们获得了光子的运动方程，并计算了黑洞周围光子轨迹的总挠度角。通过将光线分类为轨道总数，我们研究了耦合常数对直接图像，镜头环和光子环的影响。还通过与爱因斯坦 - æther理论和一般相对论进行比较来研究光轨迹的特征。此外，我们还显示了黑洞的明显光学外观，周围是薄磁盘排放，并带有三个特征发射的模型。结果表明，直接图像给出了对总通量的主要贡献，而镜头环仅给出了很小的贡献，而光子环的作用可以忽略不计。还发现光学外观显着依赖于这些耦合常数。
In Einstein-Æther theory, the Lorentz symmetry is locally broken in the high-energy regime due to the presence of theÆther field. This shall leave significant imprint on astronomical observation. In this paper, we investigate the optical appearance of two types of the static and spherically symmetric black holes in Einstein-Æther theory. Via Euler-Lagrange equation, we obtain the equations of motion of the photon and calculate the total deflection angle of the photon trajectory around the black hole. By classifying the light rays with the total number of orbits, we study the effects of coupling constants on the direct image, lensing ring, and photon ring. The features of the light trajectories are also investigated by comparing with the Einstein-Æther theory and general relativity. Moreover, we also show the explicit optical appearance of black holes surrounded by thin disk emissions with three characteristic emitted models. The results indicate that the direct image gives the main contribution to the total flux, and the lensing ring just gives a very small contribution, whereas the role of the photon ring is negligible. The optical appearances are also found to significantly rely on these coupling constants.
