Metastability of Electron-Nuclear Astrophysical Plasmas: Motivations, Signals and Conditions
Physical motivations indicating that the electron-nuclear plasma of a stellar core (like the solar core) is not in a global thermodynamical equilibrium but satisfies the conditions of a metastable
Nonextensive Statistical Effects on Nuclear Astrophysics and Many-Body Problems
Density and temperature conditions in many stellar core (like the solar core) imply the presence of nonideal plasma effects with memory and long-range interactions between particles. This aspect
CNO reaction rates and chemical abundance variations in dense stellar plasma
In the hot interiors of dense stellar plasma, the equilibrium CNO cycle converts most of the carbon and oxygen into nitrogen. We discuss implications of new measurements concerning the modified
Nonlinear dynamics and statistical effects on the relativistic nuclear equation of state
On the basis of the Tsallis' nonextensive thermostatistics, we study a generalized relativistic thermodynamics and the equation of state for an ideal gas. These results are extended to derive the
Solar resonant diffusion waves as a driver of terrestrial climate change
Negentropy in Many-Body Quantum Systems
Negentropy (negative entropy) is the negative contribution to the total entropy of correlated many-body environments. Negentropy can play a role in transferring its related stored mobilizable energy


Long-term evolution of stellar self-gravitating systems away from thermal equilibrium: connection with nonextensive statistics.
In a self-gravitating N-body system confined in an adiabatic wall, it is shown that the quasiequilibrium sequence arising from the Tsallis entropy plays an important role in characterizing the transient states away from the Boltzmann-Gibbs equilibrium state.
Thermal distributions in stellar plasmas, nuclear reactions and solar neutrinos
The physics of nuclear reactions in stellar plasma is reviewed with special emphasis on the importance of the velocity distribution of ions. Then the properties (density and temperature) of the
Non-extensive statistics, fluctuations and correlations in high-energy nuclear collisions
Abstract. Starting from the experimental evidence that high-energy nucleus–nucleus collisions cannot be described in terms of superpositions of elementary nucleon–nucleon interactions, we analyze the
RAPID COMMUNICATION: The dissipative effect of thermal radiation loss in high-temperature dense plasmas
A dynamical model based on the two-fluid dynamical equations with energy generation and loss is obtained and used to investigate the self-generated magnetic fields in high-temperature dense plasmas
Stars and statistical physics: A teaching experience
The physics of stars, their workings and their evolution, is a goldmine of problems in statistical mechanics and thermodynamics. We discuss many examples that illustrate the possibility of deepening
