Signatures of binary evolution processes in massive stars

TL;DR

This paper reviews how binary evolution processes influence massive star development, emphasizing the roles of stellar winds, rotation, and mass transfer, and their implications for stellar populations in starburst regions.

Contribution

It provides a comprehensive analysis of binary evolution effects on massive stars, integrating single star processes and binary interactions.

Findings

Rotation significantly affects binary evolution.

Mass transfer during Roche lobe overflow alters stellar evolution.

Close binary pairs are crucial for understanding stellar populations.

Abstract

Before binary components interact, they evolve as single stars do. We therefore first critically discuss massive single star processes which affect their evolution, stellar wind mass loss and rotation in particular. Next we consider binary processes and focus on the effect of rotation on binary evolution and on the mass transfer during Roche lobe overflow. The third part highlights the importance of close pairs on the comprehension of the evolution of stellar populations in starburst regions.
