The Long Period K + Be Binary HR 2577 (MWC 827)

Parsons, Sidney B.; Dempsey, Robert C.; Bopp, Bernard W.

New spectroscopic observations near Hα 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 Hα emission from the Be component undergoes considerable variations typical of its class. The presenc…

The IUE Spectrum of CN 1-2 (=PK 326 -10 1): A Southern Counterpart to V1016 Cygni and HM Sagittae?

Feibelman, Walter A.

Low-dispersion IUE spectra confirm that the emission-line object Cn 1-2 is a symbiotic star and not a planetary nebula. The UV spectrum of Cn 1-2 strongly resembles those of V1016 Cyg and HM Sge. The object is correctly identified in the finder field of Allen's Catalogue of Symbiotic Stars (1984) but misidentified in the Catalogue of Galactic Plan…
