  journal={Europhysics Letters},
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
The nonextensive statistical ensembles with dual thermodynamic interpretations
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
Slowing down of charged particles in dusty plasmas with power‐law kappa‐distributions
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
Strong evidences for a nonextensive behavior of the rotation period in open clusters
Time-dependent nonextensivity in a stellar astrophysical scenario combines nonextensive entropic indices qK derived from the modified Kawaler's parametrization, and q, obtained from rotational
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
The nonextensive parameter as a stability criterion of convection in a fluid
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
Power-law distributions and fluctuation-dissipation relation in the stochastic dynamics of two-variable Langevin equations
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
A Nonextensive Entropy Approach to Solar Wind Intermittency
The probability distribution functions (PDFs) of the differences of any physical variable in the intermittent, turbulent interplanetary medium are scale dependent. Strong non-Gaussianity of solar
The thermodynamic stability criterion in a self-gravitational system with phase transition
In this paper, we analyze the heat capacity in a self-gravitational system, where there are two phases, in the framework of nonextensive statistical mechanics. We define one value which is the ratio

To check the validity of the theory of nonextensive statistical mechanics, we have investigated the nonextensive degree of the solar interior and have tried to find the experimental evidence by
