Title: Nuclear equation of state for neutron stars and core-collapse supernovae with the variational method
The equation of state (EOS) for dense nuclear matter is an essential ingredient for understanding the properties of neutron stars and core-collapse supernovae (SNe). Though the structure of neutron stars has been studied with various nuclear theories, the number of nuclear EOSs available for SN simulations is limited. Furthermore, those SN-EOSs are based on phenomenological models for uniform nuclear matter. Therefore, we have constructed a new type of SN-EOS based on the realistic nuclear Hamiltonian composed of the Argonne v18 two-body potential and Urbana IX three-body potential using the variational many-body theory. In this talk, we will discuss the properties of our SN-EOS and its application to numerical simulations of core-collapse SNe. Furthermore, we will report on an extension of our variational approach so as to treat hyperon mixing.
