We study the nonextensive parameter for the rotating astrophysical systems with power-law distributions, including both the rotating self-gravitating system and the rotating space plasma. We extend the equation of the nonextensive parameter to a complex system with arbitrary force field , and derive a general equation of the q-parameter, most generally including both the rotating self-gravitating systems and the rotating space plasmas. At the same time, we reproduce the κ-distribution in space…

The viscosity of charged particles in the weakly ionized plasma with power-law distributions
We study the viscosity of light charged particles in weakly ionized plasma with the power-law q-distributions by using the Boltzmann equation of transport and the motion equation of hydrodynamics.
Quasiequilibrium self-gravitating systems
Because of the long-range nature of the gravitational interaction, self-gravitating systems never reach thermal equilibrium in the thermodynamic limit but remain trapped in nonequilibrium stationary

Abstract.The nonextensive statistical ensembles are revisited for the complex systems with long-range interactions and long-range correlations. An approximation, the value of nonextensive parameter
A nonextensive approach for understanding the van der Waals’ equation
In order to improve the teaching of statistical physics in universities, in this article we introduce nonextensive statistics, a new statistical theory about complex systems. We study the two
The diffusion of charged particles in the weakly ionized plasma with power-law kappa-distributions
We study the diffusion of charged particles in the weakly ionized plasma with the power-law kappa-distributions and without magnetic field. The electrons and ions have different kappa-parameters. We

We study the slowing down of a particle beam passing through the dusty plasma with power‐law κ‐distributions. Three plasma components, electrons, ions, and dust particles, can have a different

The nonextensive parameter and Tsallis distribution for self-gravitating systems
The properties of the nonextensive parameter q and the Tsallis distribution for self-gravitating systems are studied. A mathematical expression of q is deduced based on the generalized Boltzmann

TIME-DEPENDENT NONEXTENSIVITY ARISING FROM THE ROTATIONAL EVOLUTION OF SOLAR-TYPE STARS
Nonextensive formalism is a generalization of the Boltzmann–Gibbs statistics. In this formalism, the entropic index q is a quantity characterizing the degree of nonextensivity and is interpreted as a
Nonextensivity in the solar neighborhood
In the present study, we analyze the radial-velocity distribution as a function of different stellar parameters such as stellar age, mass, rotational velocity and distance to the Sun for a sample of

We apply the nonextensive statistical theory given by Landau and Lifshitz to study the stability condition of convection in a fluid. When introducing Du's equation (Du J. L., Europhys. Lett., 67

We show that the general two-variable Langevin equations with inhomogeneous noise and friction can generate many different forms of power-law distributions. By solving the corresponding stationary
