Properties of strange quark matter and strange quark stars
European Physical Journal C: Particles and Fields, 2021 A Polyakov chiral $$\text {SU(3)}$$ SU(3) quark mean-field (PCQMF) model is applied to study the properties of strange quark matter (SQM) and strange quark star (SQS) in $$\beta $$ β -equilibrium.

Quark-quark interaction and quark matter in neutron stars [PDF]
Physical Review C, 2022 Hyperon ($Y$) mixing in neutron-star matter brings about a remarkable softening of the equation of state (EoS) and the maximum mass is reduced to a value far less than $2M_{\odot}$. One idea to avoid this "hyperon puzzle in neutron stars" is to assume that the many-body repulsions work universally for every kind of baryons.

Dense hadron star in quark degree of freedom
EPJ Web of Conferences, 2014 The quark degree of freedom may play an important role as one studies dense hadron stars which can help to understand the universe origin. We add a temperature dependence to the effective quark mass adopted from a quark-quark interaction on the QCD basis

Probing the composition of sub-millisecond rotating compact stars by r-modes instability [PDF]
, 2012 We investigate the implications of the r-modes instability on the composition of a compact star rotating at a sub-millisecond period. In particular, the only viable astrophysical scenario for such an object, wich might present inside the Low Mass X-ray ...

Three-layered compact star in modified Buchdahl-I spatial metric with distinct equations of state
Physics Letters B, 2023 We present a singularity free and smoothly connected complete solution for a three-layered compact star with deconfined quark matter core surrounded by coherent quantum fluid of a Bose-Einstein condensate, all enclosed under a thin envelope of a ...

Nucleation of quark matter in neutron stars cores [PDF]
, 2004 We consider the general conditions of quark droplets formation in high density neutron matter. The growth of the quark bubble (assumed to contain a sufficiently large number of particles) can be described by means of a Fokker-Planck equation.

Quakes in solid quark stars [PDF]
Astroparticle Physics, 2004 A starquake mechanism for pulsar glitches is developed in the solid quark star model. It is found that the general glitch natures (i.e., the glitch amplitudes and the time intervals) could be reproduced if solid quark matter, with high baryon density but low temperature, has properties of shear modulus = 10^{30~34} erg/cm^3 and critical stress _c =

The Hadron-quark Crossover in Neutron Star within Gaussian Process Regression Method
The Astrophysical Journal, 2022 The equations of state of the neutron star at the hadron-quark crossover region are interpolated with the Gaussian process regression (GPR) method, which can reduce the randomness of present interpolation schemes.

Effects of quark matter and color superconductivity in compact stars [PDF]
, 2003 The equation of state for quark matter is derived for a nonlocal, chiral quark model within the mean field approximation. We investigate the effects of a variation of the form factors of the interaction on the phase diagram of quark matter under the ...
