Abstract: 

The formalism of memory functions was used to investigate the dynamic and spectral features (including a quantitative comparison of the times of correlation subside and statistical memory) of discrete time signals of X-ray activity of the microquasar XTE J1550-564. Observations of the X-ray emission dynamics were carried out from the board of the orbiting observatory Rossi X-Ray Timing Explorer. A distinguishable character of relaxation processes and memory effects in equi- and non-equidistant dynamics of the XTE J1550-564 X-ray emission was found from our analysis of temporal and event correlations. The procedure under consideration can be used for study a wide range of astrophysical phenomena and processes associated with the event-driven performance.
