Top: Results from a fully resolved DNS of a propagating flame at ﹩10^{9}\ \mathrm{g}\,\ \mathrm{cm}\,^{-3}﹩ performed with FLASH and the aprox19 network. Shown are abundances for p, ⁴He, ¹²C, ¹⁶O, ²⁰Ne, ²⁴Mg, ²⁸Si, ⁵⁴Fe, and ⁵⁶Ni plotted against the distance from the flame position so that the flame is propagating to the left. The small "tails" at the right are artifacts of the match head used to ignite the flame. The simulation was run on an adaptive mesh with an effective resolution of ﹩7.81\times 10^{-6}﹩ cm. Bottom: Results from an isochoric simulation at ﹩10^{9}\ \mathrm{g}\,\ \mathrm{cm}\,^{-3}﹩ performed with the self‐heating 19 nuclide network aprox19. Shown are the same abundances as the top panel plotted against the time and the calculated distance. The distance scaling along the top axis was obtained by multiplying the time by the flame speed with respect to the (expanded) ash.
