Quark matter and quark stars in a quasiparticle model

We investigate the properties of the equation of state of strange-quark matter and u-d quark matter, the sound velocity of quark matter, the stability region for star matter, the maximum mass of quark stars (QSs), and the tidal deformability for QSs by using a quark quasiparticle model. Our results indicate that the recently discovered heavy compact stars PSR J0348 + 0432, MSR J0740 + 6620, and PSR J2215 + 5135, and especially the GW190814s secondary component m(2) can be well described as QSs within the quasiparticle model.
