Sahade, J.; West, R. M.; Skul'Sky, M. Yu.

RY Scuti, the 11-day [Fe III] eclipsing binary, has been reinvestigated on the basis of spectrographic material obtained in Chile at the European Southern Observatory, La Silla, and at the Cerro Tololo Interamerican Observatory, covering the spectral regions 3400-5150 Å and 5700-6700 Å . Ultraviolet IUE observations were also analyzed. The spectru…
