Empirically, Type Ia supernovae are the most useful, precise, and mature tools for determining astronomical distances. Acting as calibrated candles they revealed the presence of dark energy and are being used to measure its properties. However, the nature of the Type Ia explosion, and the progenitors involved, have remained elusive, even after seven decades of research. But now, new large surveys are bringing about a paradigm shift--we can finally compare samples of hundreds of supernovae to… Expand

Despite vast improvements in the measurement of the cosmological parameters, the nature of dark energy and an accurate value of the Hubble constant (H0) in the Hubble–Lemaitre law remain unknown. ToExpand
CONSTRAINING TYPE Ia SUPERNOVAE PROGENITORS FROM THREE YEARS OF SUPERNOVA LEGACY SURVEY DATA
While it is generally accepted that Type Ia supernovae are the result of the explosion of a carbon-oxygen white dwarf accreting mass in a binary system, the details of their genesis still elude us,Expand
Progenitors of type Ia supernovae
Type Ia supernovae (SNe Ia) play an important role in astrophysics and are crucial for the studies of stellar evolution, galaxy evolution and cosmology. They are generally thought to be thermonuclearExpand

TLDR
The major supernova cosmology surveys, the presented analyses and their conclusions, together with the present status of the field are described, and the expectations for the near future are concluded. Expand
NORMAL TYPE Ia SUPERNOVAE FROM VIOLENT MERGERS OF WHITE DWARF BINARIES
One of the most important questions regarding the progenitor systems of Type Ia supernovae (SNe Ia) is whether mergers of two white dwarfs can lead to explosions that reproduce observations of normalExpand
On Silicon Group Elements Ejected by Supernovae Type Ia
There is evidence that the peak brightness of a Type Ia supernova is affected by the electron fraction Y-e at the time of the explosion. The electron fraction is set by the aboriginal composition ofExpand

Type Ia Supernovae and their implications for cosmology
Models for Type Ia Supernovae (SNe Ia) are reviewed. It is shown that there are strong reasons to believe that most SNe Ia represent thermonuclear disruptions of C-O white dwarfs, when these whiteExpand
Type I Supernovae
Several projects involving Type I supernovae and their impact on nucleosynthesis are described. 1) A major effort is underway to compute the spectrum at epochs near maximum light. 2) DynamicalExpand
The binary progenitor of Tycho Brahe's 1572 supernova
TLDR
A survey of the central region of Tycho's supernova remnant, around the position of the explosion, finds a type G0–G2 star, similar to the authors' Sun in surface temperature and luminosity (but lower surface gravity), which appears to be the surviving companion of the supernova. Expand
The Progenitors of Type Ia Supernovae
Type Ia supernovae are identified as exploding degenerate stars. Their luminosity is due to the radioactive decay of about a solar mass of 56Ni through 56Co to 56Fe. As such they are a major sourceExpand
Detection of Circumstellar Material in a Normal Type Ia Supernova

The spectroscopic detection of circumstellar material in a normal type Ia supernova explosion indicates that this material was ejected from the progenitor system. Expand
PROMPT Ia SUPERNOVAE ARE SIGNIFICANTLY DELAYED
The time delay between the formation of a population of stars and the onset of type Ia supernovae (SNe Ia) sets important limits on the masses and nature of SN Ia progenitors. Here, we use a newExpand

Analytic solutions for light curves, effective temperatures, and broad-band colors of Type I supernovae are presented. The method is generalized to include effects of finite (large) initial radiusExpand
Tycho Brahe’s 1572 supernova as a standard type Ia as revealed by its light-echo spectrum
TLDR
An optical spectrum of Tycho Brahe’s supernova near maximum brightness is obtained from a scattered-light echo more than four centuries after the direct light from the explosion swept past the Earth, finding that SN’1572 belongs to the majority class of normal type Ia supernovae. Expand
The diversity of type Ia supernovae from broken symmetries
TLDR
Multi-dimensional modelling of the explosion physics and radiative transfer reveals that the breaking of spherical symmetry is a critical factor in determining both the width–luminosity relation and the observed scatter about it. Expand
A Common Explosion Mechanism for Type Ia Supernovae
TLDR
A systematic spectral analysis of a large sample of well-observed type Ia supernovae finds that allsupernovae have low-velocity cores of stable iron-group elements and suggests that their progenitors had the same mass. Expand
