Scalar field quasinormal frequencies of Reissner-Nordstrom black hole surrounded by quintessence by using the continued fraction method

摘要

We evaluate the quasinormal modes of massless scalar field around Reissner-Nordstrom black hole surrounded by a static and spherically symmetric quintessence using the continued fraction method. The appropriate Frobenius series for three special cases of the quintessence parameter is an element of = -1/3,-2/3 and -1 are derived successfully. We show the variation of quasinormal frequencies with charge of the black hole and the quintessential parameters. The numerical results show that quintessence field decreases oscillation frequencies of all angular momentum l modes and increases the damping time of l > 0 modes.
