非对易Einstein-Euler-Heisenberg黑洞的阴影

Shadow of a noncommutative inspired Einstein-Euler-Heisenberg black hole

Marco Maceda, Alfredo Macías, Daniel Martínez-Carbajal

摘要:

使用非对易启发的爱因斯坦-欧拉-海森堡黑洞,我们分析了相关的引力子和光环,它们与事件视界一起提供了构建其阴影的必要组件。对受非对易启发的爱因斯坦-欧拉-海森堡黑洞的角半径的分析表明,对于位于其附近的观察者来说,与对易情况相比,它变得更小;随着非对易性的增加,这种影响更加明显。讨论了非对易Einstein-Euler-Heisenberg星的临界稳定束缚轨道和光子逃逸的临界角的存在性。

英文摘要:

Using a noncommutative inspired Einstein-Euler-Heisenberg black hole, we analyse the associated graviton and light rings that together with the event horizon, provide the necessary components to build its shadow. An analysis of the angular radius of the noncommutative inspired Einstein-Euler-Heisenberg black hole shows that for observers located in its vicinity, it becomes smaller when compared with the commutative case; this effect is more noticeable as noncommutativity increases. The existence of marginally stable bound orbits and the critical angle for the escaping of photons of a noncommutative inspired Einstein-Euler-Heisenberg star is also discussed.
