cds-question@unistra.frastronomical-modelssupernovaeWe construct the equation of state (EOS) of dense matter covering a wide range of temperature, proton fraction, and density for the use of core-collapse supernova simulations. The study is based on the relativistic mean-field (RMF) theory, which can provide an excellent description of nuclear matter and finite nuclei. The Thomas-Fermi approximation in combination with assumed nucleon distribution functions and a free energy minimization is adopted to describe the non-uniform matter, which is composed of a lattice of heavy nuclei. We treat the uniform matter and non-uniform matter consistently using the same RMF theory. We present two sets of EOS tables, namely EOS2 and EOS3. EOS2 is an update of our earlier work published in 1998 (EOS1; see 1998NuPhA.637..435S and 1998PThPh.100.1013S), where only the nucleon degree of freedom is taken into account. EOS3 includes additional contributions from {Lambda} hyperons. The effect of {Lambda} hyperons on the EOS is negligible in the low-temperature and low-density region, whereas it tends to soften the EOS at high density. In comparison with EOS1, EOS2 and EOS3 have an improved design of ranges and grids, which covers the temperature range T=0.1-10^2.6^MeV with the logarithmic grid spacing {delta}log_10_(T/[MeV])=0.04 (92 points including T=0), the proton fraction range Y_p_=0-0.65 with the linear grid spacing {Delta}Y_p_=0.01 (66 points), and the density range {rho}_B_=10^5.1^-10^16^g/cm^3^ with the logarithmic grid spacing {Delta}log_10_({rho}_B_/[g/cm^3^])=0.1 (110 points).2011ApJS..197...20Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/197/20CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/416/276 : Eq. of State in Magnetic Neutron Stars (Rognvaldsson+ 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/197/20https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/197/20http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/197/20https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/197/20https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/197/20http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/197/20GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/ApJS/197/20/eos2EOS2 model of core-collapse SN simulationYp[0/1] Proton fractionmeta.numberfloatisoTPlot this isothermmeta.ref.urlcharisodPlot this iso-densitymeta.ref.urlcharnBBaryon number densityfm**-3meta.id;meta.maindoubleT[0/400] TemperatureMeVphys.temperaturedoublelogpB[5.1/16] Log of baryon mass densitylog(g.cm**-3)phys.densityfloatFFree energy per baryon (G1)MeVphys.energydoubleEintInternal energy per baryon (G2)MeVphys.energydoubleS/kEntropy per baryon (in units of Boltzmann's k)stat.fit.paramdoubleAMass number of heavy nucleusphys.atmol.weightfloatZCharge number of heavy nucleusphys.atmol.numberfloatM*NEffective nucleon massMeVphys.massdoubleXn[0/1] Free neutron fractionphys.abundfloatXp[0/1] Free proton fractionphys.abundfloatXa[0/1] {alpha}-particle fractionphys.abundfloatXA[0/1] heavy nucleus fractionphys.abundfloatPPressureMeV.fm**-3phys.pressuredoublemunChemical potential of the neutron (G3)MeVphys.energy;phys.atmol.leveldoublemupChemical potential of the proton (G3)MeVphys.energy;phys.atmol.leveldoubleJ/ApJS/197/20/eos3EOS3 model of core-collapse SN simulation, includes additional contributions from {Lambda} hyperonsisoTPlot this isothermmeta.ref.urlcharXn[-0.5/1] Free neutron fractionphys.abundfloatT[0/400] TemperatureMeVphys.temperaturedoublelogpB[5.1/16] Log of baryon mass densitylog(g.cm**-3)phys.densityfloatnBBaryon number densityfm**-3meta.id;meta.maindoubleYp[0/1] Proton fractionmeta.numberfloatisodPlot this iso-densitymeta.ref.urlcharFFree energy per baryon (G1)MeVphys.energydoubleEintInternal energy per baryon (G2)MeVphys.energydoubleS/kEntropy per baryon (in units of Boltzmann's k)stat.fit.paramdoubleAMass number of heavy nucleusphys.atmol.weightfloatZCharge number of heavy nucleusphys.atmol.numberfloatM*NEffective nucleon massMeVphys.massdoubleXp[0/1] Free proton fractionphys.abundfloatXa[0/1] Alpha-particle fractionphys.abundfloatXA[0/1] heavy nucleus fractionphys.abundfloatPPressureMeV.fm**-3phys.pressuredoublemunChemical potential of the neutron (G3)MeVphys.energy;phys.atmol.leveldoublemupChemical potential of the proton (G3)MeVphys.energy;phys.atmol.leveldoubleM*LEffective {Lambda} hyperion massMeVphys.massdoubleXL[0/1.5] {Lambda} hyperion fractionphys.abundfloat
