In conclusion, the models of lightcurve and spectrum make it possible to reproduce the observations relatively accurately but their predictive capacity remains limited. The fact that the effects 3d are not taken into account and that opacities and the models of radiative transport present coarse simplifications prevents from being able to impose strong constraints on the various models of explosion.
However, although the distinction between a delayed detonation and a pure deflagration seems difficult by comparing the spectra and the synthetic lightcurves, the models under the mass of Chandrasekhar cannot account for the observations.
