Heliosheath: Diffusion Entropy Analysis and Nonextensivity q-Triplet    [PDF]

A. Haubold, H. J. Haubold, D. Kumar

In this paper we investigate the scaling behavior, based on Diffusion Entropy
Analysis and Standard Deviation Analysis, of the magnetic field strength
fluctuations recorded by Voyager-I in the heliosphere. The Voyager-I data set
exhibits scaling behavior and may follow Levy-type probability distribution. A
general fractional-order spatial and temporal diffusion model could be utilized
for the interpretation of this Levy-type behavior in comparison to Gaussian
behavior. This result confirms earlier studies of scaling behavior of the
heliospheric magnetic field strength fluctuations based on non-extensive
statistical mechanics leading to the determination of the nonextensivity
q-triplet.
