A new equation of state for core-collapse supernovae based on realistic nuclear forces and including a full nuclear ensemble

Understand

We have constructed a nuclear equation of state (EOS) that includes a full nuclear ensemble for use in core-collapse supernova simulations.

• It is based on the EOS for uniform nuclear matter that two of the authors derived recently, applying a variational method to realistic two- and there-body nuclear forces.
• We utilize an extended liquid drop model of heavy nuclei and a quantum-theoretical mass evaluation for light nuclei.
• In addition to realistic nuclear forces, the inclusion of in-medium effects on the full ensemble of nuclei makes the new EOS one of the most realistic EOS's for supernova simulations.
