The "double final fate" of super-AGB stars and its possible consequences for some astrophysical issues

TL;DR

This paper explores the dual evolutionary outcomes of super-AGB stars—either as white dwarfs or supernovae—and examines their implications for globular cluster enrichment and nucleosynthesis.

Contribution

It introduces the concept of the 'double final fate' of super-AGB stars and discusses its potential impact on astrophysical phenomena.

Findings

Super-AGB stars can end as either neon-oxygen white dwarfs or electron-capture supernovae.

The double final fate influences the chemical enrichment of globular clusters.

It affects the nucleosynthesis of s-process nuclei.

Abstract

Super-AGB stars can conclude their evolution either as neon-oxygen white dwarfs or as electron-capture supernovae. We discuss the possible consequences of the existence of this "double final fate" in the self-enrichment of globular clusters and in the nucleosynthesis process of s-nuclei.
