Determination of instabilities in the NGC 5427 circumnuclear disk
Abstract
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.
