Delay time distribution of type Ia supernovae: theories vs. observations

Research output: Chapter in Book/Report/Conference proceedingMeeting abstract (Book)

Abstract

The delay time distribution (DTD) is a powerful tool to learn more about the progenitors of type Ia supernovae (SNe Ia) and the binary evolution leading up to these events. Both can be constrained by comparing the observed DTDs with those predicted under various assumptions by a population synthesis code. In this respect, we discuss the merits and shortcomings of various formation scenarios, binary evolutionary assumptions and parameters, etc. This includes some novelties in our code, such as the treatment of accretion onto white dwarfs, merger criterions, core growth and He-star evolution. We also discuss the results of a comparison between different groups performing population synthesis studies to clarify the origin of discrepancies in their predictions concerning DTDs. We finally investigate how including the age-metallicity relation and/or the metallicity distribution of G-type dwarfs in the study may help to impose constraints, by providing a testbed for the SN Ia-affected chemical evolution of the Milky Way Galaxy.
