Title: Be Stars: Rapidly Rotating Pulsators
Authors: Th. Rivinius

I will show that Be stars are, without exception, a class of rapidly rotating stars, which are in the majority of cases pulsating stars as well, while none of them does possess a large scale (i.e. with significant dipolar contribution) magnetic field.

Title: Magnetic fields in classical Be stars
Authors: R. Yudin, S. Hubrig, M. Pogodin, I. Savanov, M. Schoeller, G. Peters, M. Cure

We report the results of our study of magnetic fields in a sample of Be stars using spectropolarimetric data obtained at the European Southern Observatory with the multi-mode instrument FORS1 installed at the 8m Kueyen telescope. The detected magnetic fields are rather weak, not stronger than ~150G. A few classical Be stars display cyclic variability of the magnetic field with periods of tens of minutes.
