The equation of state of supernova matter
We develop a variational theory of hot dense matter which generalizes the zero temperature variational methods to finite temperatures without any orthogonality corrections. This method can be used to calculate the equation of state for matter in supernovae, protoneutron stars and also heavy-ion collisions using only realistic two nucleon and three nucleon forces as inputs. We present some resul...
متن کاملRelativistic Equation of State of Nuclear Matter for Supernova Explosion
We construct the equation of state (EOS) of nuclear matter at finite temperature and density with various proton fractions within the relativistic mean field (RMF) theory for the use in the supernova simulations. We consider nucleus, alpha-particle, proton and neutron in equilibrium at densities smaller than about ρB ∼ 10 14.2g/cm3 by minimizing the free energy of the nuclear matter. The calcul...
متن کاملRelativistic Equation of State of Nuclear Matter for Supernova and Neutron Star
We construct the equation of state (EOS) of nuclear matter using the relativistic mean field (RMF) theory in the wide density, temperature range with various proton fractions for the use of supernova simulation and the neutron star calculations. We first construct the EOS of homogeneous nuclear matter. We use then the Thomas-Fermi approximation to describe inhomogeneous matter, where heavy nucl...
متن کاملEquation of State for Mercury
An analytical equation of state by Song and Mason is developed to calculate the PVT properties ofmercury. The equation of state is based on the statistical-mechanical perturbation theory of hard convexbodies and can be written as a fifth-order polynomial in the density. There exists three temperaturedependentparameters in the equation of state; the second virial coefficient, an effective molecu...
متن کاملReconstructing the cosmic equation of state from supernova distances.
Observations of high-redshift supernovae indicate that the Universe is accelerating. Here we present a model-independent method for estimating the form of the potential V(phi) of the scalar field driving this acceleration, and the associated equation of state w(phi). Our method is based on a versatile analytical form for the luminosity distance D(L), optimized to fit observed distances to dista...
