Physical Review D, 1978
We analyze models of quark matter appropriate to the description of matter at densities found within neutron stars. We consider in detail two models: quantum chromodynamics with a bag constant B = 56 MeV/fm/sup 3/, and quantum chromodynamics with B = 0.

Stability of Quark Star Models
Communications in Theoretical Physics, 2016Summary: In this paper, we investigate the stability of quark stars with four different types of inner matter configurations; isotropic, charged isotropic, anisotropic and charged anisotropic by using the concept of cracking. For this purpose, we have applied local density perturbations technique to the hydrostatic equilibrium equation as well as on ...

Soviet Physics Journal, 1974
The basic parameters — mass and radius — of the quark configurations having central densities from 1019 to 1032 g/cm3 are obtained. It is shown that similar objects should have large gravitational mass defects. The curve of the stable configurations is extended to the region of densities substantially exceeding those of the nucleus.

Brown Dwarfs, Quark Stars, and Quark-Hadron Phase Transition
Physical Review Letters, 1994It is shown that within an effective model of QCD, the Lee-Wick model, bodies with quark content of mass of the order of ${10}^{\ensuremath{-}2}$ to one solar mass can be formed at a temperature $T\ensuremath{\sim}1$ MeV much lower than the quark-hadron phase transition temperature.

STABILITY OF QUARK MATTER AND QUARK STARS
New Worlds in Astroparticle Physics, 2003We use the confining chromodielectric model to study quark matter. In the version of the model with a quartic potential for the confining field we obtain two solutions for the mean-field equations. The resulting equations of state for strange quark matter are degenerate at large densities with a small energy barrier between them.
