论文摘要
我们研究了Lobo等人建议的新型黑色弹跳时空中的两个光子球反射。这可能对应于Schwarzschild黑洞，常规的黑洞和一个可穿越的虫洞，包括Ellis-Bronnikov虫洞。在某种情况下，虫洞的喉咙充当光子球，并且在喉咙外面有另一个光子球。将太阳作为光源，观察者和虫洞按以下顺序排成一列，阳光在喉咙外面略微反射，外部光子球体的外部和内部几乎可以到达观察者。我们表明，外部光子球反射的光线在情况下是重新验证的光曲线。
We investigate retrolensing by two photon spheres in a novel black-bounce spacetime suggested by Lobo et al. which can correspond to a Schwarzschild black hole, a regular black hole, and a traversable wormhole including an Ellis-Bronnikov wormhole. In a case, the wormhole has a throat which acts as a photon sphere and it has another photon sphere outside of the throat. With the sun as a light source, an observer, and the wormhole are lined up in this order, sunlight reflected slightly outside of the throat and barely outside and inside of the outer photon sphere can reach the observer. We show that the light rays reflected by the outer photon sphere are dominant in retrolensing light curves in the case.
