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

open access: diamondEuropean 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]

open access: goldThe 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

open access: yesEuropean 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

Strange quark mass dependence of strange quark star properties

open access: yesEuropean 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}} >

Binary neutron star mergers as a probe of quark-hadron crossover equations of state [PDF]

open access: greenPhysical 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]

open access: diamondEuropean Physical Journal C: Particles and Fields
In 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]

open access: yesSciPost 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 ...
