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 star matter at finite temperature in a quasiparticle model [PDF]
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

The Hadron-quark Crossover in Neutron Star within Gaussian Process Regression Method [PDF]
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.

Quark star matter in heavy quark stars
European Physical Journal C: Particles and Fields, 2021 We study the thermodynamic properties of asymmetric quark matter and large mass quark stars within the confined-isospin-density-dependent-quark-mass model. We find that the quark matter symmetry energy should be very large in order to describe the recent

Binary neutron star mergers as a probe of quark-hadron crossover equations of state [PDF]
Physical Review D, 2022 It is anticipated that the gravitational radiation detected in future gravitational wave (GW) detectors from binary neutron star (NS) mergers can probe the high-density equation of state (EOS).

Quark star matter within an extended quasiparticle model [PDF]
European Physical Journal C: Particles and FieldsIn this work, we extend the quasiparticle model to include the chemical potential dependence of the coupling constant g and consider the density-dependent bag constant $$B_m$$ B m in order to satisfy the asymptotic freedom feature.

Quark formation and phenomenology in binary neutron-star mergers using V-QCD [PDF]
SciPost Physics, 2022 Using full 3+1 dimensional general-relativistic hydrodynamic simulations of equal- and unequal-mass neutron-star binaries with properties that are consistent with those inferred from the inspiral of GW170817, we perform a detailed study of the quark ...
