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.

Was GW190814 a Black Hole-Strange Quark Star System? [PDF]
, 2021 We investigate the possibility that the low mass companion of the black hole in the source of GW190814 was a strange quark star. This possibility is viable within the so-called two-families scenario in which neutron stars and strange quark stars coexist.

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

Magnetostatics of a superconducting quark star [PDF]
, 1993 The superconducting properties of a strange quark star are investigated using the relativistic theory of superconductivity for a fermion system. A dynamical density-dependent quark mass model is used for confinement.

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 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.

ANALYTICAL MODELS FOR QUARK STARS [PDF]
International Journal of Modern Physics D, 2007 We find two new classes of exact solutions to the Einstein–Maxwell system of equations. The matter content satisfies a linear equation of state consistent with quark matter; a particular form of one of the gravitational potentials is specified to generate solutions.

Constraints from LIGO/Virgo and NICER on quark star equation of state [Preprint title v.1] [PDF]
, 2021 We investigate the quark star equation of state within the Bayesianstatistical approach using the widely-used bag model, assuming the strangequark matter is in the color-flavor locked phase.
