Query: Three-dimensional pure deflagration models with nucleosynthesis and
  synthetic observables for Type Ia supernovae   We investigate whether pure deflagration models of Chandrasekhar-mass
carbon-oxygen white dwarf stars can account for one or more subclass of the
observed population of Type Ia supernova (SN Ia) explosions. We compute a set
of 3D full-star hydrodynamic explosion models, in which the deflagration
strength is parametrized using the multispot ignition approach. For each model,
we calculate detailed nucleosynthesis yields in a post-processing step with a
384 nuclide nuclear network. We also compute synthetic observables with our 3D
Monte Carlo radiative transfer code for comparison with observations. For weak
and intermediate deflagration strengths (energy release E_nuc <~ 1.1 x 10^51
erg), we find that the explosion leaves behind a bound remnant enriched with 3
to 10 per cent (by mass) of deflagration ashes. However, we do not obtain the
large kick velocities recently reported in the literature. We find that weak
deflagrations with E_nuc ~ 0.5 x 10^51 erg fit well both the light curves and
spectra of 2002cx-like SNe Ia, and models with even lower explosion energies
could explain some of the fainter members of this subclass. By comparing our
synthetic observables with the properties of SNe Ia, we can exclude the
brightest, most vigorously ignited models as candidates for any observed class
of SN Ia: their B - V colours deviate significantly from both normal and
2002cx-like SNe Ia and they are too bright to be candidates for other
subclasses.
