Abstract

We present a resume of the results of three di?erent studies of Be stars. The first study is about a search for Be star candidates in the LMC, the second study is related to the first systematic search for Be star candidates in the direction of the Galactic Bulge, and the third study is about the analysis of infrared L-band spectra of 13 outbursting Galactic Be stars. © 2009: Instituto de Astronomía, UNAM.
