Research output: Contribution to journalArticlepeer-review


Two data sets of metastable states duration time: one obtained in a laboratory thermal convection experiment and another in the satellite's Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI: 2002-2003 yy) observations, are compared in order to extract an information about a general (common) statistical mechanism in the onset of the metastable states. Simple probability distributions for both data sets show the same distinctive power-law (with exponent -1.1±0.1) and the exponential tails. More sophisticated analysis with moving average moments reveals a specific critical-like clusterization of the data in the both data sets with remarkably close values of the exponents.
