Strange stars with a mirror-dark-matter core confronting with the observations of compact stars

نویسندگان

چکیده

We investigate the structure and tidal deformability of strange stars (SSs) with a mirror-dark-matter (MDM) core for standard MIT bag model. find that to explain observations PSR J0740+6620, J0030+0451 GW170817 simultaneously, SSs in should have MDM although it is unnecessary J0740+6620 contain core. Our study leads result model, compact mentioned above confirm existence dark-matter inside SSs.

Strange Quark Matter and Compact Stars

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 forms found in the Universe which, together with the unprecedented progress in observational astronomy, makes such stars superb astrophysical laboratories for a broad range of most striking physical phenomena. These r...

Metastable strange matter and compact quark stars

Strange quark matter in beta equilibrium at high densities is studied in a quark confinement model. Two equations of state are dynamically generated for the same set of model parameters used to describe the nucleon: one corresponds to a chiral restored phase with almost massless quarks and the other to a chiral broken phase. The chiral symmetric phase saturates at around five times the nuclear ...

Strange matter in rotating compact stars

We have constructed equations of state involving various exotic forms of matter with large strangeness fraction such as hyperon matter, Bose-Einstein condensates of antikaons and strange quark matter. First order phase transitions from hadronic to antikaon condensed and quark matter are considered here. The hadronic phase is described by the relativistic field theoretical model. Later those equ...

Strange Quark stars: Observations & Speculations

Two kinds of difficulties have challenged the physics community for many years: (1) knowing nature’s building blocks (particle physics) and (2) understanding interacting many-body systems (many-body physics). Both of them exist in the research of quark matter and compact stars. This paper addresses the possibility that quark clustering, rather than a color super-conducting state, could occur in...

Compact stars with color superconducting quark matter

We study compact stars that contain quark matter. We look at the effect of color superconductivity in the quark matter on the nuclear-quark matter transition density, mass-radius relationship, and the density discontinuity at the boundary between nuclear and quark matter. We find that color superconducting quark matter will occur in compact stars at values of the bag constant where ordinary qua...
