Type Iax supernovae are stellar explosions that are spectroscopically similar to some type Ia supernovae at the time of maximum light emission, except with lower ejecta velocities. They are also distinguished by lower luminosities. At late times, their spectroscopic properties diverge from those of other supernovae, but their composition (dominated by iron-group and intermediate-mass elements) suggests a physical connection to normal type Ia supernovae. Supernovae of type Iax are not rare; they… Expand
Type Iax Supernovae
Type Iax supernovae (SN Iax), also called SN 2002cx-like supernovae, are the largest class of peculiar white dwarf (thermonuclear) supernovae, with over fifty members known. SN Iax have lower ejectaExpand
Investigating the diversity of supernovae type Iax: a MUSE and NOT spectroscopic study of their environments
SN 2002cx-like Type Ia supernovae (also known as SNe Iax) represent one of the most numerous peculiar SN classes. They differ from normal SNe Ia by having fainter peak magnitudes, faster declineExpand
An Excess of Mid-Infrared Emission from the Type Iax SN 2014dt
Supernovae Type Iax (SNe Iax) are less energetic and less luminous than typical thermonuclear explosions. A suggested explanation for the observed characteristics of this subclass is a binaryExpand
Pre-explosion companion stars in Type Iax supernovae
Type Iax supernovae (SNe Iax) are proposed as one new sub-class of SNe Ia since they present observational properties that are sufficiently distinct from the bulk of SNe Ia. SNe Iax are the mostExpand
Constraining Type Iax supernova progenitor systems with stellar population age dating
Type Iax supernovae (SNe~Iax) are the most common class of peculiar SNe. While they are thought to be thermonuclear white-dwarf (WD) SNe, SNe~Iax are observationally similar to, but distinct fromExpand
Observational properties of thermonuclear supernovae
The explosive death of a star as a supernova is one of the most dramatic events in the Universe. Supernovae have an outsized impact on many areas of astrophysics: they are major contributors to theExpand
On the Progenitor System of the Type Iax Supernova 2014dt in M61
We present pre-explosion and post-explosion Hubble Space Telescope images of the Type Iax supernova (SN Iax) 2014dt in M61. After astrometrically aligning these images, we do not detect any stellarExpand
Circumstellar properties of Type Ia supernovae from the helium star donor channel
We investigate predicted circumstellar properties of Type Ia supernova progenitor systems with non-degenerate helium star donors. It has been suggested that systems consisting of a carbon+oxygenExpand
Astrophysics: Portrait of a doomed star
TLDR
The detection of a progenitor in deep observations of NGC 1309, the host galaxy of SN 2012Z, obtained with the Hubble Space Telescope and including the location of the supernova before its explosion suggest thatSN 2012Z was probably an explosion of a white dwarf accreting from a helium-star companion.

An unusual white dwarf star may be a surviving remnant of a subluminous Type Ia supernova
TLDR
Strong evidence indicates that this partially burnt remnant was ejected following a subluminous Type Ia supernova event, which supports the viability of single-degenerate supernova progenitors. Expand

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.
