Non-radial pulsations have also been considered as the origin of various observed  small scale \citep[e.g., line profile variability, ][]{1996ApJS..103..475F,1997A&A...327..699F} and large scale phenomena components, ][]{1988MNRAS.233..123P,1995ApJ...452L..53M,1997A&A...327..281K,2002A&A...388..587P}  at the surface or in the wind of massive OB stars.  Non-radial g-mode pulsations were also recently proposed as the origin
