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.
