论文摘要
强大的古典引力甚至量子重力的领域正在等待探索。在这封信中,我们考虑了最近检测到的三个系统,该系统由两颗恒星和一个不挑剔的黑洞组成。通过对该系统的公开观察,我们通过在虫洞另一侧寻找轨道扰动而进行了最敏感的测试,以实现黑洞是否实际上是虫洞。在Perturber上获得的质量限制比S2绕SGR A*绕的S2旋转的S2的观察值要好得多。我们还考虑了脉冲星的观察结果如何测试脉冲星孔二进制中的黑洞是否是虫洞。与S2相似的轨道上的脉冲星是$ \ sim10 $比S2观察值更敏感的数量级。对于恒星质量的名义脉冲星孔二元,具有与Hulse-Taylor二进制脉冲星的轨道大小相似,一年的观察可能会对Perturber的质量限制为$ \ sim6 $的巨大级数,比Sgrsar周围的Pulsar的量度更好。对于可能存在于银河系中心附近可能存在的脉冲星黑孔二进制组,可以获得Pulsar-Sgr〜A*与Hulse-Taylor病例之间的一系列限制。
The realm of strong classical gravity and perhaps even quantum gravity are waiting to be explored. In this letter we consider the recently detected triple system composed of two stars and a non-accreting black hole. Using published observations of this system we conduct the most sensitive test to date for whether the black hole is actually a wormhole by looking for orbital perturbations due to an object on the other side of the wormhole. The mass limit obtained on the perturber is $\sim4$ orders of magnitude better than for observations of S2 orbiting the supermassive black hole at Sgr A*. We also consider how observations of a pulsar could test for whether the black hole in a pulsar-black hole binary is a wormhole. A pulsar in a similar orbit to S2 would be $\sim10$ orders of magnitude more sensitive than observations of S2. For a nominal pulsar-black hole binary of stellar masses, with orbital size similar to that of the Hulse-Taylor binary pulsar, one year of observations could set a mass limit on a perturber that is $\sim6$ orders of magnitude better than observations of a pulsar around Sgr~A*. A range of limits between the pulsar-Sgr~A* and Hulse-Taylor cases could be obtained for a possible population of pulsar-black hole binaries that may exist near the galactic center.
