Abstract

We present our first nucleosynthesis results from a numerical simulation of the thermonuclear disruption of a static cold Chandrasekhar-mass ¹²C/¹⁶O white dwarf. The two-dimensional simulation was performed with an adaptive-mesh Eulerian hydrodynamics code, flash, that uses as a flame capturing scheme the evolution of a passive scaler. To compute the isotopic yields and their velocity distribution, 10,000 massless tracer particles are embedded in the star. The particles are advected along streamlines and provide a Lagrangian description of the explosion. We briefly describe our verification tests and preliminary results from post-processing the particle trajectories in (ρ, T) with a modest (214 isotopes) reaction network.
