摘要：
Recently, a parametrized Schwarzschild metric(PSM) was proposed, in which n = 2 to solve the differences of mass of M87*from different observations. We find the axial gravitational quasinormal modes of this metric are unstable for n > 1. The decay rate of the quasinormal mode of the case n < 1 is much smaller than the case n = 1, which can be used to differentiate the PSM from a Schwarzschild one.
