Abstract

We discuss the development of a new computational infrastructure to enable the rapid incorporation of the latest nuclear physics results in astrophysics models. This infrastructure includes programs that simplify the generation of reaction rates, manage rate databases, visualize reaction rates, run element synthesis simulations, and visualize simulation results, all hosted at the website www.nucastrodata.org. Features of the program suite and future development are presented. © 2005 Elsevier B.V. All rights reserved.
