Fractal Analysis of X-Ray Emission from Centaurus X-3 Observed by GINGA
Abstract
X-ray time series data from the 4.8-second binary pulsar Cen X-3 observed by Ginga were analyzed. We studied the fractal dimension of the X-ray intensity of the total 1.7--37 keV energy band. The fractal dimension of the temporal behavior on time scales >= 4.8 s is comparatively large (<= 7). This implies that the variability of this source is characterized by perturbations having a small size compared with the system scale. The existence of a lower dimensional (large-scale) motion with a time scale of 500 s is suggested.
