论文摘要
黑洞的性质是重力物理学中最令人兴奋的问题之一。如果有一个异国情调的物体作为紧凑的物体作为黑洞，但没有地平线，则在合并后可能会产生重力波。在这项工作中，我们表明，对于极端质量比纳里，即使在紧凑型二元合并的灵感阶段，外来紧凑型物体的硬表面的存在也会在引力波上产生可检测的信号。我们预测，一旦Ligo-Virgo-Kagra，Einstein望远镜或宇宙探险家检测到这种来源，我们的模型表明，一个人可以在灵感阶段的表面限制比当前水平更好的启发阶段的表面。
The nature of black holes is one of most exciting issues in gravitational physics. If there is an exotic compact object as the compact as a black hole but without a horizon, gravitational wave echoes may be produced after the merger. In this work, we show that for extreme-mass-ratio binaries, even during the inspiraling phase of compact binary coalescence, the exists of hard surface of the exotic compact object will produce detectable signals on the gravitational waves. We predict that once the LIGO-Virgo-KAGRA, Einstein Telescope or Cosmic Explorer detect such kind of sources, our model shows that one can constrain the properties of surfaces of the compact objects in inspiraling stage better than the current level.
