摘要: We present the result of a search for southern Galactic Be star candidates within group miscellaneous variables ASAS-2 catalog variable stars, using statistical, morphological, photometric, and color criteria. This lead us to obtain 213 new candidates. The I-band light curves these show outbursts (Type-1 stars) only in 9% sample, stochastic variations (Type-4 91% sample. do not find stars showing clear high low states (Type-2 or simultaneously (Type-1/Type-2 stars). Our sample provide valuable bright targets resolution spectroscopic studies with small/medium size telescopes.
