Type Ia supernovae are thought to occur when a white dwarf made of carbon and oxygen accretes sufficient mass to trigger a thermonuclear explosion. The accretion could be slow, from an unevolved (main-sequence) or evolved (subgiant or giant) star (the single-degenerate channel), or rapid, as the primary star breaks up a smaller orbiting white dwarf (the double-degenerate channel). A companion star will survive the explosion only in the single-degenerate channel. Both channels might contribute… 
A search for a surviving companion in SN 1006
Multiple channels have been proposed to produce Type Ia supernovae, with many scenarios suggesting that the exploding white dwarf accretes from a binary companion pre-explosion. In almost all cases,
HUNTING FOR THE PROGENITOR OF SN 1006: HIGH-RESOLUTION SPECTROSCOPIC SEARCH WITH THE FLAMES INSTRUMENT
Type Ia supernovae play a significant role in the evolution of the universe and have a wide range of applications. It is widely believed that these events are the thermonuclear explosions of
Long-term evolution of surviving companion stars of Type Iax supernovae
The nature of the progenitors and explosion mechanism of Type Iax supernovae (SNe Iax) remain a mystery. The single-degenerate (SD) systems that involve the incomplete pure deflagration explosions
Evolution of Main-sequence-like Surviving Companions in Type Ia Supernova Remnants
Recent theoretical and numerical studies of Type Ia supernovae (SNe Ia) explosions within the single-degenerate scenario suggest that the nondegenerate companions could survive during the supernova
A RECONNAISSANCE OF THE POSSIBLE DONOR STARS TO THE KEPLER SUPERNOVA
The identity of Type Ia supernova progenitors remains a mystery, with various lines of evidence pointing toward either accretion from a nondegenerate companion or the rapid merger of two degenerate
Signatures of a Surviving Helium-star Companion in Type Ia Supernovae and Constraints on the Progenitor Companion of SN 2011fe
Single-degenerate (SD) binary systems composed of a white dwarf and a nondegenerate helium (He)-star companion have been proposed as the potential progenitors of Type Ia supernovae (SNe Ia). The
Search for Surviving Companions of Progenitors of Young LMC SN Ia Remnants
We have used two methods to search for surviving companions of Type Ia supernova progenitors in three Balmer-dominated supernova remnants in the Large Magellanic Cloud: 0519–69.0, 0505–67.9 (DEM
Where are the double-degenerate progenitors of Type Ia supernovae?
Double white dwarf binaries with merger time-scales smaller than the Hubble time and with a total mass near the Chandrasekhar limit (i.e. classical Chandrasekhar population) or with high-mass
Tycho's Supernova: The View from Gaia
SN 1572 (Tycho Brahe’s supernova) clearly belongs to the Ia (thermonuclear) type. It was produced by the explosion of a white dwarf (WD) in a binary system. Its remnant has been the first of this

Exclusion of a luminous red giant as a companion star to the progenitor of supernova SN 2011fe
TLDR
The luminosity of the progenitor system (especially the companion star) is 10–100 times fainter than previous limits on other type Ia supernova progenitors systems, allowing us to rule out luminous red giants and almost all helium stars as the mass-donating companion to the exploding white dwarf.
An absence of ex-companion stars in the type Ia supernova remnant SNR 0509−67.5
TLDR
The central region of the supernova remnant SNR 0509−67.5 in the Large Magellanic Cloud contains no ex-companion star to a visual magnitude limit of 26.9 (an absolute magnitude of MV = +8.4) within a region of radius 1.43 arcseconds, which rules out all published single-degenerate models for this supernova.
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.
Single-degenerate Type Ia Supernovae Without Hydrogen Contamination
The lack of hydrogen in spectra of type Ia supernovae (SNe Ia) is often seen as troublesome for single-degenerate (SD) progenitor models. We argue that, since continued accretion of angular momentum
Supernova SN 2011fe from an exploding carbon–oxygen white dwarf star
TLDR
Early observations of type Ia supernova SN 2011fe in the galaxy M101 at a distance from Earth of 6.4 megaparsecs find that the exploding star was probably a carbon–oxygen white dwarf, and from the lack of an early shock it is concluded that the companion was likely a main-sequence star.
IMPACT OF TYPE Ia SUPERNOVA EJECTA ON BINARY COMPANIONS IN THE SINGLE-DEGENERATE SCENARIO
Type Ia supernovae are thought to be caused by thermonuclear explosions of a carbon–oxygen white dwarf in close binary systems. In the single-degenerate scenario (SDS), the companion star is

Models for the progenitor systems of Type Ia supernovae can be divided into double-degenerate systems, which contain two white dwarfs, and single-degenerate systems, which contain one white dwarf
