products at low densities to complete silicon-burning products at the highest densities, as well as electron-capture products synthesized at the deflagration stage. Detailed calculations of the nucleosynthesis in all three models are presented. In contrast to the deflagration model, the delayed detonations produce a characteristic layered structure and the yields largely satisfy constraints from Galactic chemical evolution. In the asymmetric delayed detonation model, the region filled with electron capture species (e.g., $^{58}$Ni, $^{54}$Fe) is within a shell, showing a large off-set, above the bulk of $^{56}$Ni distribution, while species produced by the detonation are distributed more spherically.'

INTRODUCTION
============

There is a consensus that Type Ia supernovae (SNe Ia) are the outcome of a thermonuclear explosion of a carbon-oxygen white dwarf (WD) (e.g., Wheeler et al. 1995; Nomoto et al. 1997; Branch 1998). For the progenitor, the Chandrasekhar-mass ($M_{\rm Ch}$) WD model has been favored for a majority of SNe Ia (e.g., Höflich & Khokhlov 1996; Nugent et al. 1997; Fink et al. 2007; Mazzali et al. 2007).
