Context. The nature of the progenitors of type Ia supernova progenitors remains unclear. While it is usually agreed that singledegenerate progenitor systems would be luminous supersoft X-ray sources, it was recently suggested that double-degenerate progenitors might also go through a supersoft X-ray phase. Aims. We aim to examine the possibility of double-degenerate progenitor systems being supersoft X-ray systems, and place stringent upper limits on the maximally possible durations of any…

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

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

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

Binary white dwarfs and decihertz gravitational wave observations: From the Hubble constant to supernova astrophysics

Context. Coalescences of binary white dwarfs represent a copious source of information for gravitational wave interferometers operating in the decihertz band. Moreover, according to the double

The white dwarf binary pathways survey – II. Radial velocities of 1453 FGK stars with white dwarf companions from LAMOST DR 4

We present the second paper of a series of publications aiming at obtaining a better understanding regarding the nature of type Ia supernovae (SN Ia) progenitors by studying a large sample of

Identification of new Galactic symbiotic stars with SALT – I. Initial discoveries and other emission line objects

We introduce the first results from an ongoing, systematic survey for new symbiotic stars selected from the AAO/UKST SuperCOSMOS H$\alpha$ Survey (SHS). The survey aims to identify and characterise

The Evolution of Compact Binary Star Systems

The formation and evolution of compact binary stars consisting of white dwarfs, neutron stars, and black holes are reviewed, including their role as progenitors of cosmologically-important thermonuclear SN Ia and AM CVn-stars, which are thought to be the best verification binary GW sources for future low-frequency GW space interferometers.

The astrophysical science case for a decihertz gravitational-wave detector

We discuss the astrophysical science case for a decihertz gravitational-wave mission. We focus on unique opportunities for scientific discovery in this frequency range, including probes of type IA

Type Ia supernovae are understood to arise from the thermonuclear explosion of a carbon–oxygen white dwarf, yet the evolutionary mechanisms leading to such events remain unknown. Many proposed

Obscuration of supersoft X-ray sources by circumbinary material : A way to hide Type Ia supernova progenitors?

Context. The progenitors of Type Ia supernovae are usually assumed to be either a single white dwarf accreting from a non-degenerate companion (the single-degenerate channel) or the result of two

THE PROGENITORS OF TYPE Ia SUPERNOVAE. II. ARE THEY DOUBLE-DEGENERATE BINARIES? THE SYMBIOTIC CHANNEL

In order for a white dwarf (WD) to achieve the Chandrasekhar mass, MC, and explode as a Type Ia supernova (SNIa), it must interact with another star, either accreting matter from or merging with it.

Upper limits on bolometric luminosities of three Type Ia supernova progenitors: new results in the ongoing Chandra archival search for Type Ia supernova progenitors

We present analysis of Chandra archival, pre-explosion data of the positions of three nearby (< 25 Mpc) type Ia supernovae, SN2011iv, SN2012cu & SN2012fr. No sources corresponding to the progenitors

THE PROGENITORS OF TYPE Ia SUPERNOVAE. I. ARE THEY SUPERSOFT SOURCES

In a canonical model, the progenitors of Type Ia supernovae (SNe Ia) are accreting, nuclear-burning white dwarfs (NBWDs), which explode when the white dwarf reaches the Chandrasekhar mass, M{sub C} .

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.

A New Evolutionary Path to Type Ia Supernovae: A Helium-rich Supersoft X-Ray Source Channel

We have found a new evolutionary path to Type Ia supernovae (SNe Ia) that has been overlooked in previous work. In this scenario, a carbon-oxygen white dwarf (C+O WD) is originated not from an

Circumstellar Material in Type Ia Supernovae via Sodium Absorption Features

It is shown that the velocity structure of absorbing material along the line of sight to 35 type Ia supernovae tends to be blueshifted, and these structures are likely signatures of gas outflows from the supernova progenitor systems.

Upper limits on bolometric luminosities of 10 Type Ia supernova progenitors from Chandra observations

We present an analysis of Chandra observations of the position of ten nearby (< 25 Mpc) type Ia supernovae, taken before the explosions. No sources corresponding to progenitors were found in any of

An upper limit on the contribution of accreting white dwarfs to the type Ia supernova rate

It is concluded that no more than about five per cent of type Ia supernovae in early-type galaxies can be produced by white dwarfs in accreting binary systems, unless their progenitors are much younger than the bulk of the stellar population in these galaxies, or explosions of sub-Chandrasekharwhite dwarfs make a significant contribution to the supernova rate.
