Analysis of Saturn main rings by continuous wavelet transform with the complex Morlet wavelet

Abstract

A new method based on continuous wavelet transform with the complex Morlet wavelet to analyze Saturn main rings is presented. It allows to investigate in detail the resonance zones and reveal the coexistence of waves with stable periods and the wave trains with a variable instant period. This method is based on the replacing the integration of the fast--oscillation function by the solution of the partial differential equations. It is shown that such an approach is an effective tool for the study the radial structure of Saturn's A, B, and C rings. All the analyzed images were obtained from the Cassini spacecraft during 2004--2005 years.
