We present our first nucleosynthesis results from a numerical simulation of the thermonuclear disruption of a static cold Chandrasekhar-mass 12 C/ 16 O white dwarf. The two-dimensional simulation was performed with an adaptive-mesh Eulerian hydrodynamics code, flash, that uses as a flame capturing s
Among the major uncertainties involved in the Chandrasekhar mass models for Type Ia supernovae are the companion star of the accreting white dwarf (or the accretion rate that determines the carbon ignition density) and the flame speed after ignition. We present nucleosynthesis results from relativel
