Distribution of maximal temperatures in the incomplete Si-burning region obtained from a suite of SNIa models. Left: one-dimensional delayed detonation models DDTc (red crosses, Badenes et al. 2005) and DDTf (red solid squares), a sub-Chandrasekhar model (blue stars) from Bravo et al. (2011, fourth row in their Table 2), and three-dimensional delayed detonation model TURB7 from Bravo et al. (2009, red empty squares,). The solid line is a fit to the data given by, . Right: three-dimensional delayed detonation models DDT3DA (red empty squares) and DDT3DB (red crosses) from Bravo & García-Senz (2008), gravitationally confined detonation model GCD1 (magenta solid triangles), pulsating reverse detonation model PRD18 (magenta empty triangles), both from Bravo et al. (2009), and sub-Chandrasekhar model C (blue stars) from García-Senz et al. (1999). The distribution of maximal temperatures in these models is approximately constant, independent of the peak temperature, unlike the models shown in the left panel.
