The Stability of an Isentropic Model for a Gaseous Relativistic Star
نویسنده
چکیده
We show that the isentropic subclass of Buchdahl’s exact solution for a gaseous relativistic star is stable and gravitationally bound for all values of the compactness ratio u[≡ (M/R), where M is the total mass and R is the radius of the configuration in geometrized units] in the range, 0 < u ≤ 0.20, corresponding to the regular behaviour of the solution. This result is in agreement with the expectation and opposite to the earlier claim found in the literature. keywords: Static Spherical Structures: Pulsational Stability, Exact Gaseous Solutions e-mail: psnegi [email protected]; [email protected]

Relativistic Stellar Models with Quadratic Equation of State
In this paper, we have obtained and presented new relativistic stellar configurations considering an anisotropic fluid distribution with a charge distribution and a gravitational potential Z(x) that depends on an adjustable parameter. The quadratic equation of state based on Feroze and Siddiqui viewpoint is used for the matter distribution. The new solutions can be written in terms of elementar...
متن کاملNonlinear Dynamical Stability of Newtonian Rotating White Dwarfs and Supermassive Stars
We prove general nonlinear stability and existence theorems for rotating star solutions which are axi-symmetric steady-state solutions of the compressible isentropic EulerPoisson equations in 3 spatial dimensions. We apply our results to rotating and nonrotating white dwarf, and rotating high density supermassive (extreme relativistic) stars, stars which are in convective equilibrium and have u...
متن کاملNon-Relativistic Limit of Neutron Beta-Decay Cross-Section in the Presence of Strong Magnetic Field
One of the most important reactions of the URCA that lead to the cooling of a neutron star, is neutron beta-decay ( ). In this research, the energy spectra and wave functions of massive fermions taking into account the Anomalous Magnetic Moment (AMM) in the presence of a strong changed magnetic field are calculated. For this purpose, the Dirac-Pauli equation for charged and neutral fermions is ...
متن کاملNonlinear Instability in Gravitational
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.
متن کاملr-modes of slowly rotating non-isentropic relativistic stars
We investigate properties of r-modes characterized by regular eigenvalue problem in slowly rotating relativistic polytropes. Our numerical results suggest that discrete r-mode solutions for the regular eigenvalue problem exist only for restricted polytropic models. In particular the r-mode associated with l = m = 2, which is considered to be the most important for gravitational radiation driven...
