Description

Recent observations have revealed the presence of both pulsations and magnetic fields in massive stars. As these phenomena can directly affect the mass-loss and the rotation rate, their impact on stellar evolution is potentially huge, with consequences for the final fate of massive stars. I will review some of the latest observational and theoretical developments in the field, focusing in particular on the impact of subsurface convection zones in hot, massive stars. These convective regions might be responsible for both the presence of stochastically excited pulsations, small scale surface magnetic fields and surface micro/macro-turbulence.
