Abstract Thermonuclear explosions from helium double-detonation sub-Chandrasekhar mass model have been considered as an alternative way for the production of type Ia supernovae (SNe Ia). In this work, we systematically studied the helium double-detonation model, in which a carbon–oxygen white dwarf (CO WD) accumulates a helium layer from a non-degenerate helium star. 

EVOLUTION OF POST-IMPACT REMNANT HELIUM STARS IN TYPE Ia SUPERNOVA REMNANTS WITHIN THE SINGLE-DEGENERATE SCENARIO

The progenitor systems of Type Ia supernovae (SNe Ia) are still under debate. Based on recent hydrodynamics simulations, non-degenerate companions in the single-degenerate scenario (SDS) should

Optical and near-IR observations of the faint and fast 2008ha-like supernova 2010ae

A comprehensive set of optical and near-infrared (NIR) photometry and spectroscopy is presented for the faint and fast 2008ha-like supernova (SN) 2010ae. Contingent on the adopted value of host

Accreting white dwarf models for type 1 supernovae. II - Off-center detonation supernovae

Supernova models based on accreting carbon-oxygen white dwarfs are presented. In these models, the explosion is triggered by the strong helium shell flash which occurs when the accretion forms a

Thermonuclear Supernovae

The application of Type Ia supernovae (SNe Ia) as distance in dicators in cosmology calls for a sound understanding of these objects. Recent years have se en a brisk development of astrophysical

The helium star donor channel for the progenitors of Type Ia supernovae

Type Ia supernovae (SNe Ia) play an important role in astrophysics, especially in the study of cosmic evolution. Several progenitor models for SNe Ia have been proposed in the past. In this paper we

The single degenerate channel for the progenitors of Type Ia supernovae

Abstract We have carried out a detailed study of the single-degenerate channel for the progenitors of type Ia supernovae (SNe Ia). In the model, a carbon-oxygen white dwarf (CO WD) accretes

Discovery of the Closest Hot Subdwarf Binary with White Dwarf Companion

We report the discovery of an extremely close, eclipsing binary system. A white dwarf is orbited by a core He-burning compact hot subdwarf star with a period as short as similar or equal to 0.04987 d

On the brightness distribution of type Ia supernovae from violent white dwarf mergers

We investigate the brightness distribution expected for th ermonuclear explosions that might result from the ignition of a detonation during the violent merger of white dwarf (WD) binaries. Violent

3D deflagration simulations leaving bound remnants: a model for 2002cx-like Type Ia supernovae

cx-like supernovae are a sub-class of sub-luminous Type Ia supernovae. Their light curves and spectra are characterized by distinct features that indicate strong mixing of the explosion ejecta. Pure

TYPE Iax SUPERNOVAE: A NEW CLASS OF STELLAR EXPLOSION

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
