Type Ia supernovae (SNe Ia) used as distance indicators for cosmology have revealed that the cosmic expansion is accelerating owing to the existence of some kind of “dark energy”, and plans are being made to discover and carefully observe numerous high-redshift SNe Ia in order to probe th...
The progenitor of a Type Ia supernova has never been seen, but the consensus is that they are the result of the thermonuclear explosion of a degenerate carbon-oxygen white dwarf (WD) star5 gaining mass in a binary system6, in contrast to the other types of supernovae, which are thought...

Delayed detonation model for type IA supernovae 来自 Semantic Scholar 喜欢 0 阅读量: 3 作者: A Khokhlov 摘要: A new delayed detonation model for type Ia supernova explosions is considered. According to the model a detonation of a massive carbon-oxygen white dwarf occurs after an episode...
Type Ic Supernovae are a type of supernova that exhibit strong Si II absorption lines in their optical spectra, similar to Type Ia supernovae. They are characterized by the absence of hydrogen and helium lines, and are known for their high luminosities and uniform temporal evolution. ...

Type Ia supernovae (SNe Ia) are generally thought to be due to the thermonuclear explosions of carbon–oxygen\\udwhite dwarfs (COWDs) with masses near the Chandrasekhar mass. This scenario, however, has two long-standing\\udproblems. First, the explosions do not naturally produce the correct...
When a massive star in a binary system explodes as a supernova, its companion star may be polluted with heavy elements from the supernova ejecta. Such pollution has been detected in a handful of post-supernova binaries1, but none of them is associated wi
