The precise nature of Type Ia supernova (SN Ia) progenitors remains amystery, but the detonation of a sub-Chandrasekhar-mass white dwarf (WD) hasbecome a promising candidate. There is a growing body of work suggesting thatthe carbon core detonation of a sub-Chandrasekhar-mass WD can be triggered bythe detonation of a helium shell accreted from a companion WD, through eitherinward shock convergence near the center or direct edge-lit detonation. This"double-detonation" SN Ia can be triggered by a small helium shell and istherefore well approximated by the detonation of a bare carbon-oxygen whitedwarf (C/O WD). The impacts of uncertainties in experimentally andtheoretically determined nuclear reaction rates on nucleosynthesis in thedetonations of sub-Chandrasekhar-mass WDs have not yet been fully explored. Weinvestigate the sensitivity of this model to nuclear reaction rateuncertainties to better constrain the nucleosynthetic yields resulting fromthese phenomena and identify the nuclear reaction rates whose uncertaintieshave the most significant impacts on nucleosynthesis. We find that the chemicalabundances, and in particular those of the iron-group elements, are relativelyinsensitive to these nuclear reaction rate uncertainties.
