Quasinormal modes of a Schwarzschild black hole surrounded by free static spherically symmetric quintessence: Electromagnetic perturbations
Abstract
In this paper, we evaluated the quasinormal modes of electromagnetic perturbation in a Schwarzschild black hole surrounded by the static spherically symmetric quintessence by using the third-order WKB approximation when the quintessential state parameter
w
q
in the range of
−1/3<
w
q
<0
. Due to the presence of quintessence, Maxwell field damps more slowly. And when at
−1<
w
q
<−1/3
, it is similar to the black hole solution in the ds/Ads spacetime. The appropriate boundary conditions need to be modified.
