Jeans’ gravitational instability and nonextensive kinetic theory
The concept of Jeans gravitational instability is rediscussed in the framework of nonextensive statistics and its associated kinetic theory. A simple analytical formula generalizing the Jeans criterion is derived by assuming that the unperturbed self-gravitating collisionless gas is kinetically described by the q-parameterized class of power law velocity distributions. It is found that the crit...
متن کاملMass Loss Timescale of Star Clusters in External Tidal Field
We investigate evolution of star clusters in external tidal field by means of N body simulations. We followed seven sets of cluster models whose central concentration and strength of the tidal field are different. We found that the mass loss timescale due to escape of stars, tmloss, and its dependence on the two-body relaxation timescale, trh,i, are determined by the strength of the tidal field...
متن کاملA simple model for Jeans instability in the presence of a constant magnetic field
Jeans instability is derived for the case of a low density self-gravitating fully ionized gas in the presence of a constant magnetic field. A new Jeans wave number, substantially enhanced by the magnetic field, is established under a suitable symmetry assumption. Nevertheless, from our present knowledge regarding the existence of primeval magnetic fields in the Universe, it appears that they ar...
متن کاملEffect of magnetic field on Jeans instability of self gravitating strongly coupled dusty plasma
The effect of the magnetic field on the Jeans instability of self-gravitating strongly coupled dusty plasma is investigated. The medium consists of extremely massive, negatively charged strongly correlated dust grains and weakly correlated Boltzmann distributed electrons and ions. The basic equations of the problem are constructed using generalized hydrodynamic model. In deriving dispersion rel...
متن کاملOn the Jeans instability during the QCD phase transition
The Jeans scale is estimated during the coexistence epoch of quark-gluon and hadron phases in the first-order QCD phase transition. It is shown that, contrary to previous claims, reduction of the sound speed is so little that the phase transition does not affect evolution of cosmological density fluctuations appreciably.
