Detailed study of quasinormal frequencies of the Kerr black hole

We compute the quasinormal frequencies of the Ken black hole using a continued fraction method. The continued fraction method first proposed by Leaver is still the only known method stable and accurate for the numerical determination of the Ken quasinormal frequencies. We numerically obtain not only the slowly but also the rapidly damped quasinormal frequencies and analyze the peculiar behavior of these frequencies at the Ken limit. We also calculate the algebraically special frequency first identified by Chandrasekhar and confirm that it coincides with the n=8 quasinormal frequency only at the Schwarzschild limit.
