The Be phenomenon, that is the ejection of matter from Be stars into acircumstellar disk, has been a long lasting mystery. In the last few years, theCoRoT (Convection, Rotation and planetary Transits) satellite brought clearevidence that Be outbursts are directly correlated with pulsations. We foundthat it may be the transport of angular momentum by waves or pulsation modesthat brings the already rapid stellar rotation to its critical value at thesurface, and allows the star to eject material. The recent discovery ofstochastically excited gravito-inertial modes by CoRoT in a hot Be starstrengthens this scenario. We present the CoRoT observations and modeling ofseveral Be stars and describe the new picture of the Be phenomenon which arosefrom these results.
