Abstract

Asteroseismology of massive stars has recently begun a revolution thanks to high-precision time series photometry from space telescopes. This has allowed accurate and robust constraints on interior physical processes, such as mixing and rotation in the near-core region of stars, to be determined across different masses and ages. In this review, I discuss recent advances in our knowledge of massive star interiors made by means of gravity-mode asteroseismology, and highlight some new observational discoveries of variability in some of the most massive stars in our universe.
