ABSTRACT
The observable consequences of a nova outburst depend sensitively on the details of the thermonuclear runaway which initiates the outburst. One of the more important sources of uncertainty is the nuclear reaction data used as input for the evolutionary calculations. A recent paper by Starrfield, Truran, Wiescher, & Sparks [1] has demonstrated that changes in the reaction rate library used within a nova simulation have significant effects, not just on the production of individual isotopes (which can change by an order of magnitude), but on global observables such as the peak luminosity and the amount of mass ejected. We will present preliminary results of systematic analyses of the impact of reaction rate uncertainties on nova nucleosynthesis. © 2000 American Institute of Physics.

    In extremely metal-poor stars ([Fe H]< 2 5), hydrogen is mixed into the convection driven by helium flash and induces neutron-capture nucleosynthesis with the reactions, 12C(p γ)13N(e+ν)13C(α n)16O, as the neutron source. We investigate the progress of this nucleosynthesis with use of...
