OPGR(DDHdeltaY4) (with hyperons)
Abstract
This EoS is based on the RMF parameterisation DDHdelta~[GNPA_2004] for cold neutron star matter in beta-equilibrium containing the baryon octet and electrons, see Ref.~[OPGR_2015] for details of the parameterisation of hyperonic interactions. For the crust, the EoS by Douchin and Haensel [DHA_2001] has been added below a density of n_B = 2.5 x 10^(-4) fm^(-3) and the inner crust has been computed following~[GPPVP_2014]. Proton fraction and compositional information is available for the core only.
