INVESTIGATION ON PROTON AND LEPTON CONCENTRATION IN SUPERNOVA EXPLOSIONS SIMULATIONS
Abstract
- This research describes the effective chiral mean field model to construct the relativistic equation of state (EOS) of nuclear matter at finite temperature and density with various proton fractions and lepton fractions for the use in the supernova simulations. This model is based on chiral symmetry and we have adopted the RMF theory with the non-linear terms, which was a success in describing the properties of both stable and unstable nuclei. In supernovae, the EOS determines the non-linear the dynamics of the collapse and the outgoing shock, and determines whether the remnant ends up as a neutron star or black hole. The various properties of supernova matter are investigated within the effective chiral mean field model. The outcome is demonstrated at zero entropy (neglecting thermal effect), the various proton fractions ranging from (Yp=0.1~0.5) and various lepton fractions ranging from (Ye=0.13~0.5) to be used for the simulations.
