We constrain the equation of state of quark stars within the Bayesian statistical approach using the mass and radius measurements of PSR J0030+0451 from NICER. Three types of bag models, with and without non-zero finite quark mass and/or superfluidity, are employed for quark stars made up with self-bound strange quark matter. We find the $90{{\ \rm per\ cent}}$ posterior credible boundary around the most probable values of the quark star maximum mass is $M_{\rm TOV}=2.38_{-0.23}^{+0.26}\, M_… Expand

Bayesian Inference of Strange Star Equation of State Using the GW170817 and GW190425 Data
The observations of compact star inspirals from LIGO/Virgo provide a valuable tool to study the highly uncertain equation of state (EOS) of dense matter at the densities in which the compact starsExpand


Cold quark matter
We perform an O({alpha}{sub s}{sup 2}) perturbative calculation of the equation of state of cold but dense QCD matter with two massless and one massive quark flavor, finding that perturbation theoryExpand
Constraints on interquark interaction parameters with GW170817 in a binary strange star scenario
The LIGO/VIRGO detection of the gravitational waves from a binary merger system, GW170817, has put a clean and strong constraint on the tidal deformability of the merging objects. From thisExpand
Probing up-down quark matter via gravitational waves
Recently, it was shown that quark matter with only $u$, $d$ quarks ($ud$QM) can be the ground state of matter for baryon number $A>A_\textrm{min}$ with $A_{\rm min}\gtrsim 300$. In this paper, weExpand
PSR J0030+0451 Mass and Radius from NICER Data and Implications for the Properties of Neutron Star Matter
Neutron stars are not only of astrophysical interest, but are also of great interest to nuclear physicists because their attributes can be used to determine the properties of the dense matter inExpand
Fast spinning strange stars: Possible ways to constrain interacting quark matter parameters
For a set of equation of state (EoS) models involving interacting strange quark matter, characterized by an effective bag constant (B_eff) and a perturbative quantum chromodynamics corrections termExpand
NNNLO pressure of cold quark matter: leading logarithm
At high baryon chemical potential mu_B, the equation of state of QCD allows a weak-coupling expansion in the QCD coupling alpha_s. The result is currently known up to and including the fullExpand
Strange stars with different quark mass scaling
We investigate the stability of strange quark matter and the properties of the cor- responding strange stars, within a wide range of quark mass scaling. The calculation shows that the resultingExpand
Color flavor locked strange matter
We analyze how the CFL states in dense matter work in the direction of enhancing the parameter space for absolutely stable phases (strange matter). We find that the "CFL strange matter" phase can beExpand
GW170817: Observation of Gravitational Waves from a Binary Neutron Star Inspiral.
The association of GRB 170817A, detected by Fermi-GBM 1.7 s after the coalescence, corroborates the hypothesis of a neutron star merger and provides the first direct evidence of a link between these mergers and short γ-ray bursts. Expand
Strange quark matter and compact stars
Abstract Astrophysicists distinguish between three different kinds of compact stars. These are white dwarfs, neutron stars, and black holes. The former contain matter in one of the densest formsExpand
