Descripción
Massive stars are the cosmic engines that shape and drive our Universe.
Many issues such as their formation, their stability and the mass loss
effects, are far from being completely understood. Recent ground-based
and space observations have shown pulsations in massive MS and post-MS
stars, such as acoustic and gravity modes excited by the
κ-mechanism and even solar-like oscillations. Theoretical studies
emphasized the presence of strange modes in massive models, and recent
theoretical analyses have shown that hot supergiants can pulsate in
oscillatory convective modes. We review the instability domains of
massive stars as well as their excitation mechanisms and present the
latest results.
