Strange quark mass dependence of strange quark star properties [PDF]
European Physical Journal C: Particles and Fields, 2021 The effects of strange quark mass on masses, radii, and tidal deformabilities of strange quark stars are studied via the quasiparticle model that includes the non-perturbative features of QCD in low density region. The constraints of $$M_{\mathrm {TOV}} >

Quark core stars, quark stars and strange stars [PDF]
Zeitschrift f�r Physik C Particles and Fields, 1989 A recent one flavor (zero temperature) quark matter equation of state is generalized to several flavors. It is shown that quarks undergo a first order phase transition. In addition, this equation of state depends on few parameters, one in the two flavor case, two in the three flavor case, and these parameters can be constrained by phenomenology.

Structure of Quark Stars [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractThis paper gives an brief overview of the structure of hypothetical strange quarks stars (quark stars, for short), which are made of absolutely stable 3-flavor strange quark matter. Such objects can be either bare or enveloped in thin nuclear crusts, which consist of heavy ions immersed in an electron gas.

Strange Quark Star (SQS) in Tolman IV potential with density dependent B-parameter and charge
European Physical Journal C: Particles and Fields, 2022 In this paper, the solutions of Einstein–Maxwell Field Equations for relativistic strange quark star in Tolman-IV potential considering MIT bag model EoS $$p=\frac{1}{3}(\rho -4B)$$ p = 1 3 ( ρ - 4 B ) of interior matter in presence of charge in higher ...

DISTINGUISHING BARE QUARK STARS FROM NEUTRON STARS [PDF]
International Journal of Modern Physics A, 2004 Observations to date cannot distinguish neutron stars from self-bound bare quark stars on the basis of their gross physical properties such as their masses and radii alone. However, their surface luminosity and spectral characteristics can be significantly different.

QUARK MATTER SYMMETRY ENERGY AND QUARK STARS [PDF]
The Astrophysical Journal, 2013 We extend the confined-density-dependent-mass (CDDM) model to include isospin dependence of the equivalent quark mass. Within the confined-isospin-density-dependent-mass (CIDDM) model, we study the quark matter symmetry energy, the stability of strange quark matter, and the properties of quark stars.

Hybrid stars with large strange quark cores [PDF]
EPJ Web of Conferences, 2022 The possible existence of hybrid stars is studied using several multiquark interaction channels. The hadronic phase consists of an equation of state (EoS) with presently accepted nuclear matter properties and the quark model is constrained by the vacuum ...

Quark star matter at finite temperature in a quasiparticle model
European Physical Journal C: Particles and Fields, 2021 We study the thermodynamic properties of asymmetric quark matter, large mass quark stars (QSs), and proto-quark stars (PQSs) within the quasiparticle model. Considering the effects of temperature within quasiparticle model can significantly influence the
