Conclusion on the modes of explosion

It thus seems that the most favoured model is that of a turbulent deflagration of dwarf white with the mass of Chandrasekhar having accrété matter of a stellar companion followed or not detonation. These models make it possible to disperse dwarf white the completion, produce speeds of expansion of the layers of stars comparable with what is observed and a quantity of ${ }^{56}$Ni making it possible to produce the good lightcurves. Lastly, the modeling of the explosive nucleosynthesis reproduces abundances actually observed in the spectra.
