2D Hydrodynamical models showing type Ia supernova explosions originated from the near-Chandrasekhar mass white dwarf.
A Model with flame transits from deflagration to detonation (DDT)
A model with flame fails the trasition to detonation.
Illustration showing the temperature evolution inside the white dwarf. Flame progression from the center of the white dwarf to the surface of the northern hemisphere ejects the highly neutronized material to the interstellar medium (ISM).
