摘要:Type Ia supernovae are the result of the thermonuclear disruption ofmassive white dwarfsmade of
carbon and oxygen, but the details of the explosionmechanismare largely unknown. Most current
explosionmodels invoke either a pure turbulent deflagration or a delayed transition to a supersonic
detonation. Although both mechanisms can coexist, and account for part of the observational
sample, only delayed detonations seem able to explain the bulk of the so-called normal Type Ia
supernovae. Here we report on two numerical experiments aimed to explore the conditions under
which a deflagration-to-detonation transition can be obtained, and their consequences
