We describe observed properties of the Type Iax class of supernovae (SNe Iax), consisting of SNe observationally similar to its prototypical member, SN 2002cx. The class currently has 25 members, and we present optical photometry and/or optical spectroscopy for most of them. SNe Iax are spectroscopically similar to SNe Ia, but have lower maximum-light velocities (2000 ≲ |v| ≲ 8000 km s−1), typically lower peak magnitudes (−14.2 ⩾ MV, peak ≳ −18.9 mag), and most have hot photospheres.

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 decline

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 from

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 ejecta

A luminous, blue progenitor system for the type Iax supernova 2012Z

The progenitors' luminosity, colours, environment and similarity to the progenitor of the Galactic helium nova V445 Puppis suggest that SN 2012Z was the explosion of a white dwarf accreting material from a helium-star companion, and observations over the next few years will either confirm or show that this supernova was actually the explosive death of a massive star.

Supernovae and their host galaxies – VII. The diversity of Type Ia supernova progenitors

We present an analysis of the light curve (LC) decline rates (Δm15) of 407 normal and peculiar supernovae (SNe) Ia and global parameters of their host galaxies. As previously known, there is a

Possible Detection of the Stellar Donor or Remnant for the Type Iax Supernova 2008ha

Type Iax supernovae (SNe Iax) are thermonuclear explosions that are related to SNe Ia, but are physically distinct. The most important differences are that SNe Iax have significantly lower luminosity

Photometric and spectroscopic observations of a slowly declining, luminous Type Ia supernova (SN Ia) SN 2011hr in the starburst galaxy NGC 2691 are presented. SN 2011hr is found to peak at M B = −

SUBCLASSES OF TYPE Ia SUPERNOVAE AS THE ORIGIN OF [α/Fe] RATIOS IN DWARF SPHEROIDAL GALAXIES

Recent extensive observations of Type Ia Supernovae (SNe Ia) have revealed the existence of a diversity of SNe Ia, including SNe Iax. We introduce two possible channels in the single degenerate

Although Type Ia supernovae (SNe Ia) are very useful in many astrophysical fields, their exact nature is still unclear, e.g., the progenitor and explosion models. The high-velocity features (HVFs) in
