Abstract

Recent discoveries in nonlinear dynamics have made it desirable to investigate various dynamical systems for evidence of chaotic behavior. An analysis of the RV Tauri variable R Scuti is presented, showing possible indications of chaos. The input data consisted of a set of times and magnitudes of maximum and minimum brightness, derived from AAVSO observations of the star.
