Massive stars are at the heart of their host galaxy’s evolution. Understanding their internal evolution is fundamental to describe, for instance, the resulting compact objects and the chemical evolution of their surroundings. One major source of uncertainty is how angular momentum transport alters their internal rotation profile. With strong influence on the chemical mixing and the evolutionary outcome, it calls for detailed study.
Asteroseismology, the study of pulsating stars, provides precise observational constraints on these important internal properties. A new treasure trove of data from space missions has enabled a leap forward in the modelling of massive stars in both the number of stars and to what detail they are modelled. We will present the recent advances in asteroseismic modelling of these stars on a population level. Next, we will also take a deep dive into one massive star, which was recently discovered as the first of its kind to host an internal magnetic field. These novel results highlight the advances in the measurement of internal rotation profiles, which indicate strong angular momentum transport and chemical mixing.
