A dynamical , confining model and hot quark stars
نویسنده
چکیده
We explore the consequences of an equation of state (EOS) obtained in a confining Dyson-Schwinger equation model of QCD for the structure and stability of nonstrange quark stars at finite-T , and compare the results with those obtained using a bag-model EOS. Both models support a temperature profile that varies over the star’s volume and the consequences of this are model independent. However, in our model the analogue of the bag pressure is (T, μ)-dependent, which is not the case in the bag model. This is a significant qualitative difference and comparing the results effects a primary goal of elucidating the sensitivity of quark star properties to the form of the EOS.

Equations of state for strange quark matter in beta equilibrium at high densities are used to investigate the structure (mass and radius) of compact objects. The chromodi-electric model is used as a general framework for the quark interactions, which are mediated by chiral mesons, σ and π, and by a confining chiral singlet dynamical field, χ. Using a quar-tic potential for χ, two equations of s...

In this article nucleons are discussed based on constituent quark model. This model aims at studying the forces among three particles and the corresponding standard two-body potential contribution. The quark potential contains a hypercentral interaction. The confining potential is composed of four components,color charge, the oscillatory potential, the interaction quark and neutral gluon, and...

In most models, mesons consist of quark -antiquark pairs moving in a confining potential. However, it would be interesting to consider the effect of an extra residual interaction by introducing the quark particles which contain a dependent spin and isospin. In the Chiral constituent quark model, the hyperfine part of the potential is provided by the interaction of the Goldstone bosons, which ...
متن کاملOn the Mechanism of Low-mass Compact Object Formation
We suggest that low-mass compact objects (hadron stars, quark stars) with M < 1 M ⊙ can appear only due to fragmentation of rapidly rotating proto-neutron stars. Such low-mass stars receive large kicks due to an explosion of a lighter companion in a pair of fragments, or due to dynamical ejection of one of the lighter components in the case when three bodies are formed. As far as low-mass compa...
متن کاملStructure of the hadron-quark mixed phase in protoneutron stars
We study the hadron-quark phase transition in the interior of hot protoneutron stars, combining the Brueckner-Hartree-Fock approach for hadronic matter with the MIT bag model or the Dyson-Schwinger model for quark matter. We examine the structure of the mixed phase constructed according to different prescriptions for the phase transition, and the resulting consequences for stellar properties. W...
