Type Ia supernovae are thought to result from thermonuclear explosions of carbon–oxygen white dwarf stars. Existing models generally explain the observed properties, with the exception of the sub-luminous 1991bg-like supernovae. It has long been suspected that the merger of two white dwarfs could give rise to a type Ia event, but hitherto simulations have failed to produce an explosion. Here we report a simulation of the merger of two equal-mass white dwarfs that leads to a sub-luminous… 
Sub-Chandrasekhar White Dwarf Mergers as the Progenitors of Type Ia Supernovae
Type Ia supernovae (SNe Ia) are generally thought to be due to the thermonuclear explosions of carbon–oxygen white dwarfs (CO WDs) with masses near the Chandrasekhar mass. This scenario, however, has
TYPE Ia SUPERNOVAE FROM MERGING WHITE DWARFS. I. PROMPT DETONATIONS
Merging white dwarfs are a possible progenitor of Type Ia supernovae (SNe Ia). Numerical models suggest that a detonation might be initiated before the stars have coalesced to form a single compact
The nebular spectra of the transitional Type Ia Supernovae 2007on and 2011iv: Broad, multiple components indicate aspherical explosion cores
The nebular-epoch spectrum of the rapidly declining, 'transitional' Type Ia supernova (SN) 2007on showed double emission peaks, which have been interpreted as indicating that the SN was the result of

Type Ia supernovae (SNe Ia) are important objects in astronomy and astrophysics. They are one of the brightest and common transients in the universe, a standard candle for a cosmic distance, and a
A hot subdwarf–white dwarf super-Chandrasekhar candidate supernova Ia progenitor
Supernova Ia are bright explosive events that can be used to estimate cosmological distances, allowing us to study the expansion of the Universe. They are understood to result from a thermonuclear
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 normal
Violent mergers of nearly equal-mass white dwarf as progenitors of subluminous Type Ia supernovae
Context. The origin of subluminous Type Ia supernovae (SNe Ia) has long eluded any explanation, because all Chandrasekhar-mass models have severe problems reproducing them. Recently, it has been
Supernovae: A smashing success
TLDR
Type Ia supernovae are potentially invaluable as cosmological distance indicators, but if they are to provide a reliable measure of the expansion history of the Universe and nature of dark energy, more evidence that they are a largely homogeneous population will be required.
Constraining Type Ia Supernova Progenitors
Abstract We present observational and theoretical studies constraining Type Ia supernova progenitors. First, we use a new observational technique to show that “prompt” SNe Ia that trace
Normal type Ia supernovae from disruptions of hybrid He-CO white-dwarfs by CO white-dwarfs
Type Ia supernovae (SNe) are thought to originate from the thermonuclear explosions of carbon-oxygen (CO) white dwarfs (WDs). The proposed progenitors of standard type Ia SNe have been studied for
