Marsakova V. Variability of the individual pulsation cycles of the long-period variables

The catalogue of the individual cycles characteristics of the 53 long-periodic variable stars has been obtained. The variability of these characteristics in time has been studied and different types of their variability have been obtained for several groups of stars. The classification of the purely investigated red variables was made using the analysis of periodicities. Correlation analysis of the individual pulsation cycles characteristics have been made for each of stars and catalogue of these correlations is listed. The range of the diagram that connect variability of individual cycles characteristics with mean parameters of stellar variability and the spectral class has been obtained. The additions to the classification of long-periodic variables based on these diagrams have been proposed.
