The coupling between pulsation and mass loss in massive stars

TL;DR

This paper explores the potential roles of pulsational instabilities in addressing key issues of mass loss, wind structure, and angular momentum redistribution in massive stars, highlighting unresolved questions in stellar astrophysics.

Contribution

It discusses the significance of pulsation in massive stars and frames critical questions about its influence on mass loss and stellar wind dynamics.

Findings

Pulsation may influence mass-loss rates in massive stars.

Pulsation could modulate stellar wind structures.

The role of pulsation in angular momentum redistribution remains uncertain.

Abstract

To what extent can pulsational instabilities resolve the mass-loss problem of massive stars? How important is pulsation in structuring and modulating the winds of these stars? What role does pulsation play in redistributing angular momentum in massive stars? Although I cannot offer answers to these questions, I hope at the very least to explain how they come to be asked.
