Theoretical Delay Time Distributions

TL;DR

This paper reviews methods for calculating theoretical delay time distributions of type Ia supernova progenitors, compares results from different research groups, and discusses factors influencing these distributions.

Contribution

It introduces a synthesis approach for delay time distributions and analyzes reasons for discrepancies among various research findings.

Findings

Retention efficiency affects single degenerate progenitor models

Differences in results are not solely due to hydrogen retention efficiency

Comparison highlights the need for further investigation into progenitor evolution

Abstract

We briefly discuss the method of population synthesis to calculate theoretical delay time distributions of type Ia supernova progenitors. We also compare the results of the different research groups and conclude that although one of the main differences in the results for single degenerate progenitors is the retention efficiency with which accreted hydrogen is added to the white dwarf core, this cannot explain all the differences.
