Be Stars: Nonradial Pulsations, Be Stars: Line Profiles

Scientific paper

The Be phenomenon is one of the most standing non-resolvd problems in stellar astrophysics. Recently, it was proposed that non-radial stellar pulsations could be a key to understand the mass loss in Be stars. Also, the study of the oscillation spectrum of a star can be used to probe its interior and therefore represents an excellent tool to improve theories of structure and evolution of the Be stars. In this paper the authors review the previous contributions in this field and give the new results from high spectral and temporal resolution and high signal-to-noise spectroscopy of the prototype non-radially pulsating Be star ζ Oph.
