Recent observations of peculiar emission-line objects with infrared excess.
Abstract
Recent optical, IR, and UV observations of Be stars are summarized. Optical observations of the prototype HD 45677 (BE IVe) are described and interpreted in terms of a model in which a normal B-type star is embedded in an extended multicomponent atmosphere. The identification of IR-excess objects on the basis of near-IR HKL photometry and five-band UV photometry from the ANS satellite is discussed.
