Chemical composition of the ejected matter in four delayed detonation models with ρ_DDT = 1.4 × 10⁷ g cm^-3. From top to bottom: hybrid WD with a M_CO = 0.74 M_⊙ (model 23); hybrid WD with M_CO = 0.3 M_⊙ (model 12); mixed model with an initial X(¹²C) = 0.20 (model 27); and pure CO WD with an initial homogeneous composition with X(¹²C) = X(¹⁶O) ≃ 0.5 and solar mass fractions of species with A ≥ 24 (model 30). The black thick line is the abundance by mass of ⁵⁶Ni a few seconds after explosion. The rest of lines give the abundance by mass of the most important elements after radioactive decays (i.e., the final stable isotopes), and have the following meaning: green stands for fuel (solid is C, short dashed is O, and long dashed is Ne); blue stands for IME (solid is Si, dotted is Mg, short dashed is S, and long dashed is Ca); and red stands for IGE (solid is Fe, dotted is Cr, short dashed is Mn, and long dashed is Ni).
