Explore a scientific lecture examining how asteroseismology reveals the internal structure and evolution of O- and B-type stars. Learn about the critical role these massive stars play in the chemical evolution of the Universe, with particular focus on their convective cores and mixing processes during the main-sequence phase. Discover how stellar oscillations detected by space telescopes like Kepler and TESS provide valuable insights into internal mixing and rotation patterns. Understand how additional mixing at the convective core boundary and radiative envelope affects these stars' lifespans and helium core mass development. Examine current uncertainties in stellar structure theory and how modern asteroseismology techniques help address these challenges through the analysis of stellar oscillation data.
