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.
