摘要
本文分析了用Ginga观测到的4.8秒双星脉冲星Cen X - 3的X射线时间序列数据。我们研究了1.7 ~ 37 keV总能带x射线强度的分形维数。时间尺度≥4.8秒时,时间行为的分形维数较大。这意味着与系统的尺度相比,源随着小尺度的扰动而变化。简要估计了噪声对分形维数的影响。文中提到存在一个时间尺度为500s的低维运动。
Fractal Analysis of X-ray Emission from Centaurus X-3 Observed with Ginga(Proceedings of the Workshop on the Hydrodynamic Study of Accretion Disks and Pulsating Stars)
X‐ray time series data from the 4.8‐second binary pulsar Cen X‐3 observed with Ginga are analyzed. We study the fractal dimension of x‐ray intensity of the total 1.7∼37 keV energy band. The fractal dimensions of the temporal behavior on time scales ≥4.8 seconds are comparatively large. It implies that the source varies with small size perturbations compared with the scale of the system. The effect of noise on the fractal dimension is estimated briefly. It is mentioned that there exists a low dimensional motion with the time scale of 500 s.
