The Properties of the Neutron Star PSR B2303+46
並列摘要
The properties of the neutron star PSR B2303 + 46 are investigated within the framework of relativistic mean field theory for the baryon octet system through adjusting the hyperon coupling constants. Models for the neutron star B2303+46 are obtained by choosing suitable hyperon coupling constants x_(σh) and x_(ωh), with x_(ρh) being determined by the constituent quark model SU (6) symmetry and the nucleon coupling constants being chosen as the set CZ11. Our results show that the field strengths of the mesons σ, ω, and ρ, the chemical potentials of the neutron and electron, the relative particle number density of the electron, muon, neutron, proton, Λ, Σ, and Ξ, and the pressure and energy density of the neutron star PSR B2303 + 46 all have an uncertain value region, respectively.
