INFORMATION AND ENTROPY REGULARITIES OF VARIABLE STARS

Abstract

Operation is devoted to a razrakbotka of methods of computer simulation to determination of entropy characteristics of signals from astrophysical objects. The possibility of the description of multifractal properties of astrophysical signals is shown. This operation is devoted to a creation method research entropy - the metric chart for the description of a status of variable stars and the quantitative characteristics distinguishing types of variable stars are defined (like Keith's World, eruptivny variables, symbiotic variable and others). It is shown a possibility of theoretical, quantitative classification of variable stars, detailing and disclosures of the new physical regularities adding Gertsshprunga-Ressel's chart. It is shown that the offered new method allows to classify quantitatively razklichny types of variable stars by a time series of their brightness: cepheids, zatmenno-variable stars, red giants, white dwarfs, objkekt of the principal sequence of the star chart etc. Building such dependence for signals of different nature, it is possible to classify them by the quantitative criteria of stochasticity, self-similarity, self-affinity, regular, self-organization, and based on it to draw conclusions about the physical nature of the appropriate astrophysical processes.

Keywords: Information, entropy, variable stars, metrics – topological characteristics, a brightness curve, it is entropy - the metric chart, classification.
