The importance of neutrino opacities for the accretion luminosity in spherically symmetric supernova models
M. Liebendoerfer, O. E. B. Messer, A. Mezzacappa +3
Based on general relativistic three-flavor Boltzmann neutrino transport, we compare simulations of the postbounce evolution for five different stellar progenitors with 13 and 20 so…
Stellar Sources of the Interstellar Medium
F. -K. Thielemann, D. Argast, F. Brachwitz +14
With the exception of the Big Bang, responsible for 1,2H, 3,4He, and 7Li, stars act as sources for the composition of the interstellar medium. Cosmic rays are related to the latter…
Nuclear Reaction Rate Uncertainties and their effects on Nova Nucleosynthesis Modeling
W. Raphael Hix, Michael S. Smith, Anthony Mezzacappa +2
The nucleosynthesis and other observable consequences of a nova outburst depend sensitively on the details of the thermonuclear runaway which initiates the outburst. One important…
Computational Methods for Nucleosynthesis and Nuclear Energy Generation
W. R. Hix, F. -K. Thielemann
This review concentrates on the two principle methods used to evolve nuclear abundances within astrophysical simulations, evolution via rate equations and via equilibria. Because i…
