Equation-of-state table with hyperon and antikaon for supernova and neutron star merger.

Abstract (from CDS):

We develop a new equation-of-state (EOS) table involving thermal (anti)kaons, Bose-Einstein condensate of K mesons, and Λ-hyperons for core-collapse supernova and neutron star merger simulations. This EOS table is based on a finite-temperature, density-dependent relativistic hadron field theory where baryon-baryon interaction is mediated by scalar σ, vector ω, and ρ mesons, using the parameter set DD2 for nucleons. The repulsive hyperon-hyperon interaction is mediated by an additional strange ph meson. The EOS for the K condensed matter is also calculated within the framework of the relativistic mean field model, whereas the low-density, inhomogeneous matter is calculated in the extended nuclear statistical equilibrium model. The EOS table is generated for a wide range of values of three parameters-baryon density (10–12 to ∼1 fm–3), positive charge fraction (0.01-0.60), and temperature (0.1-158.48 MeV).
