| Abstract: |
We report first results from a spectroscopic monitoring campaign of 581 southern
B-type stars. Our multi-epoch spectra allow to derive the multiplicity rate as
a function of spectral type from B0 to B9. Additionally, a number of
previously unknown Be stars have been discovered raising the frequency of the
Be phenomenon in our sample from 7% to at least 18%. The similar binary
fraction in Be stars and in “normal” B-type stars argues against a
companion-induced Be phenomenon. |
