Strange quark mass dependence of strange quark star properties
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}} >

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.

Chinese Journal of Astronomy and Astrophysics, 2006 Members of the family of pulsar-like stars are distinguished by their different manifestations observed, i.e., radio pulsars, accretion-driven X-ray pulsars, X-ray bursts, anomalous X-ray pulsars/soft gamma-ray repeaters, compact center objects, and dim thermal neutron stars. Though one may conventionally think that these stars are normal neutron stars,

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.

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.

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

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 =
