Properties of strange quark matter and strange quark stars

open access: yesEuropean 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.

Dense hadron star in quark degree of freedom

open access: yesEPJ 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

Pulsar slow glitches in a solid quark star model [PDF]

open access: yes, 2008
A series of five unusual slow glitches of the radio pulsar B1822-09 (PSR 1825-0935) was observed between 1995 and 2005. This is a phenomenon that is understood in a solid quark star model, and reasonable parameters for slow glitches are given in this ...

ISPSR B0943+10 a low-mass quark star? [PDF]

open access: yes, 2006
A recent X-ray observation has shown that the radio pulsar PSR B0943 + 10, with clear drifting subpulses, has a much smaller polar cap area than that of conventional pulsars with mass of similar to 1 M-circle dot and radius of similar to 10 km. Zhang and

Energy release due to antineutrino untrapping and diquark condensation in hot quark star evolution [PDF]

open access: yes, 2004
We study the consequences of antineutrino trapping in hot quark matter for quark star configurations with possible diquark condensation. Due to the conditions of charge neutrality and β-equilibrium the flavor asymmetry increases with the number density ...

Three-layered compact star in modified Buchdahl-I spatial metric with distinct equations of state

open access: yesPhysics 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 ...

Gravitational waves from binary compact star mergers in the context of strange matter

open access: yesEPJ Web of Conferences, 2018
In this article we will focus on the appearance of the hadron-quark phase transition and the formation of strange matter in the interior region of the hypermassive neutron star and its conjunction with the spectral properties of the emitted gravitational
