论文摘要
耦合到高斯 - 骨网不变的标量场会发生速度不稳定性，从而导致黑洞的自发标量。到目前为止，对此效果的研究仅限于单个黑洞的空间。我们介绍了带有数值相对性模拟的黑洞二进制文件的正面碰撞和半圆形灵感的动态标量的结果。我们表明，黑洞二进制文件可以通过脱落其初始标量头发来形成标量的残留物或动态倒入。讨论了这些发现的观察意义。
Scalar fields coupled to the Gauss-Bonnet invariant can undergo a tachyonic instability, leading to spontaneous scalarization of black holes. Studies of this effect have so far been restricted to single black hole spacetimes. We present the first results on dynamical scalarization in head-on collisions and quasicircular inspirals of black hole binaries with numerical relativity simulations. We show that black hole binaries can either form a scalarized remnant or dynamically descalarize by shedding off its initial scalar hair. The observational implications of these findings are discussed.
