The sequence of nuclear reactions occurring in supernova explosions is believed to involve thousands of neutron-rich nuclei, and a knowledge of the properties of these nuclei is essential to calculating the element synthesis in these cataclysmic events. Similarly, information on proton-rich nuclei is needed to understand nova explosions occurring on the surfaces of white dwarf stars and X-ray bursts occurring on the surfaces of neutron stars. Recent measurements with radioactive beams at ORNL's Holifield Radioactive Ion Beam Facility (HRIBF) and elsewhere have prompted the evaluation of a number of reactions involving unstable nuclei needed for stellar explosion studies. Recent evaluation efforts will be presented. To ensure that the latest relevant experimental and theoretical nuclear physics results are rapidly incorporated into astrophysical models, we have created a new computational infrastructure for nuclear astrophysics data. Available on-line at www.nucastrodata.org, a simple point-and-click interface guides users to convert evaluated nuclear reaction and structure information as input into thermonuclear reaction rates in a variety of output formats. It also enables users to combine a new reaction rate with an existing library, as well as to create, merge, store, document, and share custom libraries. Future capabilities will include tools to carry out data evaluations and to calculate and visualize the synthesis of elements in astrophysical environments. The site www.nucastrodata.org also features a comprehensive set of links (over 60 so far) to nuclear datasets around the world which are important for nuclear astrophysics studies.
