Abstract

We have, for the first time, determined the effect of nuclear reaction rate uncertainties on nova model predictions by simultaneously considering uncertainties in all relevant reaction rates. Our unique Monte Carlo approach enables a robust determination of uncertainties of nuclear origin in predictions of synthesized abundances, including radioisotopes which may be observable. This technique also enables us to identify which reactions most influence the production of each isotope, thereby guiding future measurements.
