论文摘要
标量是一个非常有趣的现象，允许将紧凑的物体带有标量头发，同时将所有预测都留在弱场中的限制中。在高斯 - 骨网重力中，标量场的源可以是时空的曲率。最近显示，对于标量场和高斯 - 骨网不变，自旋诱导的黑洞标量的特定类型的耦合函数是可能的。在本文中，我们通过执行相关线性标量场扰动方程的2+1时间演变来研究这种现象，并检查Kerr黑洞变得不稳定的区域，从而导致新的标量旋转的黑洞。这是研究自旋诱导标量化的发展的更直接的数值方法，可以作为对先前结果的独立检查。
The scalarization is a very interesting phenomena allowing to endow a compact object with scalar hair while leaving all the predictions in the weak field limit unaltered. In Gauss-Bonnet gravity the source of the scalar field can be the curvature of the space-time. It was recently shown that for a particular type of coupling function between the scalar field and the Gauss-Bonnet invariant, spin-induced black hole scalarization is possible. In the present paper we study this phenomenon by performing a 2+1 time evolution of the relevant linearized scalar field perturbation equation and examine the region where the Kerr black hole becomes unstable giving rise to new scalarized rotating black holes. This is more direct numerical approach to study the development of spin-induced scalarization and it can serve as an independent check of the previous results.
