Nuclear statistical equilibrium for Type Ia supernova simulations

We solve the equations of nuclear statistical equilibrium (NSE) for the mass fractions of 443 nuclides, including the effects of temperature dependent nuclear partition functions [T. Rauscher, F. Thielemann, At. Data Nucl. Data Tables 75 (2000) 1-351] and Coulomb corrections [G. Chabrier, A.Y. Potekhin, Phys. Rev. E 58 (1998) 4941]. The resulting mass fractions are then convolved with the new weak interaction rates for pf-shell nuclei based on large-scale shell model calculations [K. Langanke, G. Martinez-Pinedo, At. Data Nucl. Data Tables 79 (2001) 1-46] to get the rate of neutronization and the specific neutrino luminosity of matter in NSE. We present tables of the results and give examples of how the tables can be used in Type la supernova simulations. (C) 2008 Elsevier Inc. All rights reserved.
