Type Ia supernovae, the thermonuclear explosions of white dwarf stars composed of carbon and oxygen, were instrumental as distance indicators in establishing the acceleration of the universe's expansion. However, the physics of the explosion are debated. Here we report a systematic spectral analysis of a large sample of well-observed type Ia supernovae. Mapping the velocity distribution of the main products of nuclear burning, we constrain theoretical scenarios. We find that all supernovae have… Expand

The nebular spectra of the Type Ia supernova 1991bg: further evidence of a non-standard explosion
Type Ia supernovae (SNe Ia) come in a large range of luminosities, as determined mostly by the amount of 56Ni produced in the explosion. Nevertheless, they can be normalized and used as standardExpand
Abundance stratification in type Ia supernovae – II. The rapidly declining, spectroscopically normal SN 2004eo
The variation in properties of Type Ia supernovae, the thermonuclear explosions of Chandrasekhar-mass carbon-oxygen white dwarfs, is caused by different nucleosynthetic outcomes of these explosions,Expand
A faint type of supernova from a white dwarf with a helium-rich companion
A faint type Ib supernova is reported in the halo of the nearby isolated galaxy, NGC 1032, and it is concluded that it arises from a low-mass, old progenitor, likely to have been a helium-accreting white dwarf in a binary. Expand
Insights into thermonuclear supernovae from the incomplete Si-burning process
Type Ia supernova (SNIa) explosions synthesize a few tenths to several tenths of a solar mass, whose composition is the result of incomplete silicon burning that reaches peak temperatures of 4 GK toExpand
An asymmetric explosion as the origin of spectral evolution diversity in type Ia supernovae
It is reported that the spectral diversity is a consequence of random directions from which an asymmetric explosion is viewed, and indicates that ignition at an offset from the centre is a generic feature of type Ia supernovae. Expand
Observational Clues to the Progenitors of Type Ia Supernovae
Type Ia supernovae (SNe Ia) are important distance indicators, element factories, cosmic-ray accelerators, kinetic-energy sources in galaxy evolution, and end points of stellar binary evolution. ItExpand
Supernovae and their Nucleosynthesis
Supernovae belong to the most powerful explosions in galaxies (only γ-ray bursts seem to be more energetic). They are also the dominant sources of the elements in the Universe, as the Big Bang ledExpand
Modeling Type Ia supernova explosions
Abstract Despite their astrophysical significance–as a major contributor to cosmic nucleosynthesis and as distance indicators in observational cosmology–Type Ia supernovae lack theoreticalExpand
A Chandrasekhar Mass Progenitor for the Type Ia Supernova Remnant 3C 397 from The Enhanced Abundances of Nickel and Manganese
Despite decades of intense efforts, many fundamental aspects of Type Ia supernovae (SNe Ia) remain elusive. One of the major open questions is whether the mass of an exploding white dwarf (WD) isExpand
Neutron excess number and nucleosynthesis of heavy elements in a type Ia supernova explosion
Type Ia supernovae produce very powerful burst of light, which can be observed to high redshift. This fact is very attractive for cosmological applications. For supernova light curve modeling, it isExpand


The physics of type Ia supernovae
Abstract The basic recipe for SN Ia explosions is simple. A white dwarf in a binary system, growing towards the limiting Chandrasekhar mass, contracts and ignites under degenerate (electron gas)Expand
Type Ia Supernova Explosion: Gravitationally Confined Detonation
We present a new mechanism for Type Ia supernova explosions in massive white dwarfs. The scenario follows from relaxing assumptions of symmetry and involves a detonation born near the stellarExpand
The type Ia supernova SNLS-03D3bb from a super-Chandrasekhar-mass white dwarf star
It is shown that the high-redshift supernova SNLS-03D3bb has an exceptionally high luminosity and low kinetic energy that both imply a super-Chandrasekhar-mass progenitor, which may provide an explanation for the observed trend that overluminous type Ia supernovae occur only in ‘young’ environments.

The Thermonuclear Explosion of Chandrasekhar Mass White Dwarfs

Carbon Ignition in Type Ia Supernovae: An Analytic Model
