We explore SNe Ia as p-process sites in the framework of two-dimensional SNIa delayed detonation and pure deflagration models. The WD precursor is assumedto have reached the Chandrasekhar mass in a binary system by mass accretionfrom a giant/main sequence companion. We use enhanced s-seed distributions,obtained from a sequence of thermal pulse instabilities both in the AGB phaseand in the accreted material. We apply the tracer-particle method toreconstruct the nucleosynthesis by the thermal histories of Lagrangianparticles, passively advected in the hydrodynamic calculations. For eachparticle we follow the explosive nucleosynthesis with a detailed network forall isotopes up to 209Bi. We find that SNe Ia can produce a large amount ofp-nuclei, both the light p-nuclei below A=120 and the heavy-p nuclei, at quiteflat average production factors, tightly related to the s-process seeddistribution. For the first time, we find a stellar source able to produceboth, light and heavy p-nuclei almost at the same level as 56Fe, including thevery debated neutron magic 92,94Mo and 96,98Ru. We also find that there is animportant contribution from p-process nucleosynthesis to the s-only nuclei80Kr, 86Sr, to the neutron magic 90Zr, and to the neutron-rich 96Zr. Finally,we investigate the metallicity effect on p-process. Starting with differents-process seed distributions, for two metallicities Z = 0.02 and Z = 0.001,running SNe Ia models with different initial composition, we estimate that SNeIa can contribute to, at least, 50% of the solar p-process composition.
