Time evolution of the flame asymmetry diagnostic parameter ζ for 256³ simulations from the G, J and H simulation series (see Table 1). The bottom panel shows the simulations with EoS Coulomb corrections, and the top panel shows the simulations without. The asymmetry develops in much the same way regardless of the inclusion of Coulomb corrections in the EoS, and is even slightly more pronounced when they are included. Clearly, the Rayleigh-Taylor instability is suppressed in the highest density simulation (H01) and the flame surface becomes essentially a sphere (ζ = 0). Figure 7 shows the severity of the asymmetry for different values of ζ, which is difficult to imagine a priori.
