Nonlinear Instability in Gravitational
نویسنده
چکیده
The dynamics of gaseous stars can be described by the EulerPoisson system. Inspired by Rein’s stability result for γ > 4 3 , we prove the nonlinear instability of steady states for the adiabatic exponent γ = 6 5 in spherically symmetric and isentropic motion.

A Novel Indicator to Predict the Onset of Instability of a Gravitational Flow on a Slope
In order to present a quantitative indicator for the onset of instability, in this paper, the critical points of a stratified gravitational flow on a slope are found and analyzed. These points are obtained by means of the solution of the two-dimensional Navier-Stokes equations via the standard Arakawa-C finite-difference method. Results show that in the marginal Richardson numbers, the critical...
متن کاملA new method based on fuzzy system and gravitational optimal detector for capacitor placement, considering nonlinear loads
This paper describes an advantageous method for using the capacitor banks in the distribution network, optimally. The aim is to determine the count, location and capacitor values in order to minimize the annual cost resulting from energy losses and capacitor bank’s installation cost. Besides, in the case of having nonlinear loads in the network, by installing capacitors in appropriate locations...
متن کاملPURD-TH-99-08, astro-ph/9911218 Short-scale gravitational instability in a disordered Bose gas
We study numerically evolution of a self-gravitating nonequilibrium Bose gas contained in a fixed volume. We find that, even when the volume is small enough to prevent collisionless instability, a compact phase-correlated object (a Bose star) can form, by gravity alone, from a disordered initial state. We interpret this effect and the associated growth of the density contrast as consequences of...

متن کاملSecular Bar-Mode Evolution and Gravitational Waves From Neutron Stars
The secular instability and nonlinear evolution of the m = 2 f-mode (barmode) driven by gravitational radiation reaction in a rapidly rotating, newly formed neutron star are reviewed. There are two types of rotating bars which generate quite different gravitational waveforms: those with large internal rotation relative to the bar figure (Dedekind-like bars) have GW frequency sweeping downward d...
