چکیده
Abstract The measurement of the macroscopic properties a neutron star, whether in binary or an isolated system, provides us with key opportunity to place stringent constraint on its equation state. In this paper, we perform Bayesian model selection wide variety star equations state using multi-messenger observations. particular, (i) use mass and tidal deformability measurements from two merger events, GW170817 GW190425; (ii) simultaneous mass–radius PSR J0030+0451 J0740+6620 by NICER collaboration, while latter has been analyzed joint NICER/radio/XMM-Newton collaboration. Among 31 considered analysis, are able rule out different variants MS1 family, SKI5, H4, WFF1 decisively, which either extremely stiff soft most preferred turns be AP3 (or MPA1), predicts radius dimensionless 1.4 M ? 12.10 (12.50) km 393 (513), respectively.

Neutron Star Evolutions using Tabulated Equations of State with a New Execution Model
The addition of nuclear and neutrino physics to general relativistic fluid codes allows for a more realistic description of hot nuclear matter in neutron star and black hole systems. This additional microphysics requires that each processor have access to large tables of data, such as equations of state, and in large simulations the memory required to store these tables locally can become exces...

Methods are developed for constructing spectral representations of cold (barotropic) neutron-star equations of state. These representations are faithful in the sense that every physical equation of state has a representation of this type and conversely every such representation satisfies the minimal thermodynamic stability criteria required of any physical equation of state. These spectral repr...

Constraints on hyperon couplings from neutron star equations of state¤
Based on the constituent quark picture of baryons and taking into account the contributions of isovector and strange mesons, we have developed the extended Zimanyi-Moszkowski model of dense baryon matter for studying neutron star (NS) equations of state (EOSs). Four sets of meson-hyperons coupling constants are investigated. The rst is characterized by strong attractive § interaction while th...
