  • 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
