We have applied photometric methods to calculate the Toomre parameter of
the circumnuclear region of NGC 5427 using visible and near-infrared
Hubble Space Telescope images. We study the types of instability that
appear in the dynamics, and determine the morphology of this
circumnuclear region, from the point of view of a density wave scenario.
