Macroturbulent broadening: a single snap-shot approach to investigate pulsations in massive stars?

TL;DR

This paper explores whether macroturbulent broadening in spectral lines of massive stars can be used as a quick method to detect stellar pulsations from a single observation.

Contribution

It proposes a novel approach to study pulsations in massive stars using macroturbulent broadening as a single snapshot diagnostic.

Findings

Initial progress in understanding macroturbulent broadening

Potential for single snapshot pulsation detection

Foundation for future observational strategies

Abstract

We present a brief progress report of our project aimed at the investigation of the so-called macroturbulent broadening affecting the line-profiles of O and early B-type stars, and speculate about the possible use of this spectroscopic feature as a single snap-shot approach to investigate pulsations in massive stars.
