The long-period K + Be binary HR 2577 (MWC 827)

New spectroscopic observations near H-alpha and Na I D, along with ultraviolet IUE scans, have been obtained for the K + Be composite system HR 2577. High-precision radial-velocity measures do not support the suggested 58-year orbit of Hendry (1982). The H-alpha emission from the Be component undergoes considerable variations typical of its class. The presence of a Li I 6707 A feature as well as the IUE observations support the idea that little or no interaction between the binary components of HR 2577 is taking place.
