FROM CHAOTIC TO 1 F PROCESSES IN SOLAR MCW-BURSTS/

Solar bursts with superfine time structure observed at 2.5 and 2.85 GH z at the Crimean Astrophysical Observatory have been analyzed by means of statistical methods for nonlinear dynamical systems. Finite values of the correlation dimension have not been detected for all the studi ed events. The presence of a 1/f(gamma) component in many of the proce ssed events has been found by means of wavelet analysis and maximum li kelihood technique. The model of uncorrelated pulses is proposed as th e one capable of producing a 1/f(gamma) shape of the power spectrum. A procedure is developed for extracting the parameters of pulse sequenc es from the data, and the magnitudes of pulse duration, amplitude, and repetition frequency are estimated for the solar burst events.
