$\begin{figure} \par\includegraphics[width=8.6cm,clip]{8424fig1.eps}\end{figure}$ Figure 1: Contour map of pressure in a cut across the star at the end of the deflagration phase of model DDT3DA (t=1.55 s). The labels of the isobars give the logarithm of pressure in erg cm^-3. The axis labels are in units of 1000 km. The preservation of spherical symmetry is a consequence of the subsonic nature of the deflagration front.

The lengthscale is given in units of 1000 km s^-1, while the temperature scale is given in the side colorbar in units of 10⁹ K.

$\begin{figure} \par\includegraphics[width=8.5cm,clip]{8424fig9.eps}\end{figure}$ Figure 9: Map of the final chemical composition on a cut across the ejected matter: C-O is shown in black, intermediate-mass elements in grey, and Fe-Ni in white. The incinerated matter pervades the whole ejecta, with intermediate-mass elements dominating an annular region at intermediate radius. Unburned C-O are found in isolated pockets, mainly in the outer regions of the ejecta. The origin of the large C-O pockets seen in this figure can be traced back to features of the flame front identifiable in Figs. 2, 6, and 7.
