Context. There is general agreement that supernovae Ia correspond to the thermonuclear runaway of a white dwarf that is part of a compact binary, but the details of the progenitor systems are still unknown and much debated. One of the proposed progenitor theories is the single-degenerate channel in which a white dwarf accretes from a companion, grows in mass, reaches a critical mass limit, and is then consumed after thermonuclear runaway sets in. However, there are major disagreements about the… 

Theoretical uncertainties of the Type Ia supernova rate

It is thought that Type Ia supernovae (SNe Ia) are explosions of carbon-oxygen white dwarfs (CO WDs). Two main evolutionary channels are proposed for the WD to reach the critical density required for

On the evolution of rotating accreting white dwarfs and Type Ia supernovae

The potential importance of the angular momentum which is gained by accreting white dwarfs (WDs) has been increasingly recognized in the context of Type Ia supernova (SN Ia) single-degenerate model.

The effect of helium accretion efficiency on rates of Type Ia supernovae: double detonations in accreting binaries

The double-detonation explosion scenario of Type Ia supernovae has gained increased support from the SN Ia community as a viable progenitor model, making it a promising candidate alongside the

A closer look at non-interacting He stars as a channel for producing the old population of type Ia supernovae

The nature of the progenitors of type Ia supernovae (SNe Ia) remains a mystery. Binary systems consisting of a white dwarf (WD) and a main-sequence (MS) donor are potential progenitors of SNe Ia, in

Observational Clues to the Progenitors of Type Ia Supernovae

Type Ia supernovae (SNe Ia) are important distance indicators, element factories, cosmic-ray accelerators, kinetic-energy sources in galaxy evolution, and end points of stellar binary evolution. It

Rates and delay times of Type Ia supernovae in the helium-enriched main-sequence donor scenario

The nature of the progenitors of Type Ia supernovae (SNe Ia) remains a mystery. Comparing theoretical rates and delay-time distributions of SNe Ia with those inferred observationally can constrain


Recent observational and theoretical progress has favored merging and helium-accreting sub-Chandrasekhar mass white dwarfs (WDs) in the double-degenerate and the double-detonation channels,

Mass-accreting white dwarfs and type Ia supernovae

Type Ia supernovae (SNe Ia) play a prominent role in understanding the evolution of the Universe. They are thought to be thermonuclear explosions of mass-accreting carbon-oxygen white dwarfs (CO WDs)

The influence of mass-transfer variability on the growth of white dwarfs, and the implications for Type Ia supernova rates

White dwarfs (WDs) can increase their mass by accretion from companion stars, provided the mass-accretion rate is high enough to avoid nova eruptions. The accretion regimes that allow growth of the

Next generation population synthesis of accreting white dwarfs – I. Hybrid calculations using bse + mesa

Accreting, nuclear-burning white dwarfs (WDs) have been deemed to be candidate progenitors of Type Ia supernovae (SNe Ia), and to account for supersoft X-ray sources, novae, etc. depending on their



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


Recent theoretical and observational studies both argue that the merging of double carbon-oxygen white dwarfs (WDs) is responsible for at least some Type Ia supernovae (SNe Ia). Previous (standard)

The delay-time distribution of Type Ia supernovae: a comparison between theory and observation

Aims. We investigate the contribution of different formation scenarios for type Ia supernovae in elliptical galaxies. The single-degenerate scenario (a white dwarf accreting from a late main-sequence

Supernova Type Ia progenitors from merging double white dwarfs - Using a new population synthesis model

The study of Type Ia supernovae (SNIa) has lead to greatly improved insights into many fields in astrophysics, however a theoretical explanation of the origin of these events is still lacking. We


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

The nature of the progenitors of Type Ia supernovae (SNe Ia) is still unclear. In this paper, by considering the effect of the instability of accretion disc on the evolution of white dwarf (WD)

Type-Ia Supernova Rates and the Progenitor Problem: A Review

Abstract The identity of the progenitor systems of type-Ia supernovae (SNe Ia) is a major unsolved problem in astrophysics. SN Ia rates are providing some striking clues. We review the basics of SN

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

Discovery of the progenitor of the type Ia supernova 2007on

The discovery of an object in pre-supernova archival X-ray images at the position of the recent type Ia supernova in the elliptical galaxy NGC 1404 is reported, which favours the accretion model for this supernova, although the host galaxy is older than the age at which the explosions are predicted in the accreting models.
