We present results for a suite of fourteen three-dimensional , high resolution hydrodynamical simulations of delayed-detonation models of Type Ia supernova ( SN Ia ) explosions .
This model suite comprises the first set of three-dimensional SN Ia simulations with detailed isotopic yield information .
As such , it may serve as a database for Chandrasekhar-mass delayed-detonation model nucleosynthetic yields and for deriving synthetic observables such as spectra and light curves .
We employ a physically motivated , stochastic model based on turbulent velocity fluctuations and fuel density to calculate in situ the deflagration to detonation transition ( DDT ) probabilities .
To obtain different strengths of the deflagration phase and thereby different degrees of pre-expansion , we have chosen a sequence of initial models with 1 , 3 , 5 , 10 , 20 , 40 , 100 , 150 , 200 , 300 , and 1600 ( two different realizations ) ignition kernels in a hydrostatic white dwarf with central density of 2.9 \times 10 ^ { 9 } \mathrm { g cm ^ { -3 } } , plus in addition one high central density ( 5.5 \times 10 ^ { 9 } \mathrm { g cm ^ { -3 } } ) and one low central density ( 1.0 \times 10 ^ { 9 } \mathrm { g cm ^ { -3 } } ) rendition of the 100 ignition kernel configuration .
For each simulation we determined detailed nucleosynthetic yields by post-processing 10 ^ { 6 } tracer particles with a 384 nuclide reaction network .
All delayed detonation models result in explosions unbinding the white dwarf , producing a range of \mathrm { { } ^ { 56 } Ni } masses from 0.32 to 1.11 \mathrm { M } _ { \odot } .
As a general trend , the models predict that the stable neutron-rich iron group isotopes are not found at the lowest velocities , but rather at intermediate velocities ( { \sim } 3 , 000 - 10 , 000 \mathrm { km s ^ { -1 } } ) in a shell surrounding a \mathrm { { } ^ { 56 } Ni } -rich core .
The models further predict relatively low velocity oxygen and carbon , with typical minimum velocities around 4 , 000 and 10 , 000 \mathrm { km s ^ { -1 } } , respectively .
