论文摘要
2-2孔是对地平线对象的明确实现，它仍然非常类似于BH。普通的相对论气体可以用作2-2孔二次重力溶液的物质来源，这导致了可计算的区域法熵。在这里，我们表明，它也导致引力浪潮阻尼时，它可以转移到2-2孔的中心并再次退出。我们确定了两个频率依赖性效应，大大减少了阻尼。旋转2-2孔溶液尚不清楚，但是我们仍然能够考虑一些旋转依赖性效果。阻尼的频率和自旋依赖性有助于确定合并事件的旋转残余物中可能的回声共振信号。它还控制着巨星不稳定性的命运。
A 2-2-hole is an explicit realization of a horizonless object that can still very closely resemble a BH. An ordinary relativistic gas can serve as the matter source for the 2-2-hole solution of quadratic gravity, and this leads to a calculable area-law entropy. Here we show that it also leads to an estimate of the damping of a gravitational wave as it travels to the center of the 2-2-hole and back out again. We identify two frequency dependent effects that greatly diminish the damping. Spinning 2-2-hole solutions are not known, but we are still able to consider some spin dependent effects. The frequency and spin dependence of the damping helps to determine the possible echo resonance signal from the rotating remnants of merger events. It also controls the fate of the ergoregion instability.
