Be Stars as Seen Through Telescopes in Survey Mode (I)

Abstract

In spite of the almost all-encompassing variability of Be stars, surveys play a steadily increasing role in complementing the insights gained from single-star studies. The definition of classical Be stars as recently augmented by \cite{Rivinius2013} enables unambiguous identification of Be stars in a much increased range of observations. Results of targeted surveys are briefly reviewed for the effects of metallicity, binarity, and evolution. It still remains to be seen whether Be stars are safe benchmarks for the calibration of evolutionary models with rapid rotation.
