论文摘要
我们研究了爱因斯坦 - 加斯 - 邦网理论中自发标量黑洞的极性准标准模式。在先前的著作中，我们表明，在径向[2]和轴向扰动[3]下，研究模型的基本分支的一组无节结晶解决方案稳定。在这里，我们计算了极性准模式，并表明这组溶液也针对极性扰动也是稳定的。因此，对于参数空间的某个区域，标量的黑洞可能是稳定的物理上有趣的对象。极性准模式的频谱与Schwarzschild的频谱均不同，该模式与Schwarzschild One差异，该模式提供了通过未来的重力波观测来测试高斯河网理论的可能性。
We study the polar quasinormal modes of spontaneously scalarized black holes in Einstein-Gauss-Bonnet theory. In previous works we showed that a set of nodeless solutions of the fundamental branch of the model studied in [1] are stable under both radial [2] and axial perturbations [3]. Here we calculate the polar quasinormal modes and show that this set of solutions is stable against the polar perturbations as well. Thus for a certain region of the parameter space the scalarized black holes are potentially stable physically interesting objects. The spectrum of the polar quasinormal modes differs both quantitatively and qualitatively from the Schwarzschild one which offers the possibility to test the Gauss-Bonnet theory via the future gravitational wave observations.
