Modeling He-rich subdwarfs through the Hot-Flasher scenario: First Results

TL;DR

This paper explores the Hot-Flasher scenario for forming helium-rich subdwarf stars through evolutionary simulations of deep and shallow mixing cases across various metallicities.

Contribution

It introduces the first simulation-based analysis of the Hot-Flasher scenario focusing on different mixing types and metallicities for He-enriched subdwarfs.

Findings

Different mixing cases lead to distinct surface compositions.

Metallicity influences the evolution and surface properties of the stars.

Initial results support the Hot-Flasher scenario as a viable formation channel.

Abstract

We present first results from evolutionary simulations aimed at exploring the Hot-Flasher scenario for the formation of H-deficient subdwarf stars. The two types of late hot flashers that lead to He-enriched surfaces, "deep" and "shallow" mixing cases, are investigated for different metallicities.
