What is the role of wind mass transfer in the progenitor evolution of Type Ia Supernovae?

TL;DR

This paper investigates how wind mass transfer from asymptotic giant branch stars influences the evolution of binary systems leading to Type Ia supernovae, challenging simplified assumptions in previous models.

Contribution

It provides a detailed analysis of wind mass transfer effects on binary evolution and assesses the significance of AGB stars as progenitors of SNe Ia.

Findings

Wind mass transfer significantly affects binary evolution pathways.

AGB stars may play a more substantial role in SNe Ia progenitors than previously thought.

Results suggest revisions to population-synthesis models for SNe Ia.

Abstract

Type Ia supernovae (SNe Ia) are thermonuclear explosions of carbon-oxygen white dwarfs (WDs) that accrete mass from a binary companion, which can be either a non-degenerate star (a main-sequence star or a giant) or an other WD in a binary merger (single- and double-degenerate scenario, respectively). In population-synthesis studies of SNe Ia the contribution of asymptotic giant branch (AGB) stars to either scenario is marginal. However, most of these studies adopt simplified assumptions to compute the effects of wind mass loss and accretion in binary systems. This work investigates the impact of wind mass transfer on a population of binary stars and discusses the role of AGB stars as progenitors of SNe Ia.
