We study the equation of state (EOS) of nuclear matter at finite temperature density with various proton fractions for use in supernova simulations. The properties of nuclear matter with both uniform and non-uniform distributions are studied consistently. We also discuss the EOS of neutron star matter at zero temperature in a wide density range including hyperons antikaons quarks. The EOS of neutron star matter could be softened by incorporating these new degrees of freedom.
