Scientific paper

Light curves in the J, K and L infrared bands are presented for the eclipsing binary RZ Scutum. Observations at 1.2, 2.2 and 3.8 microns were made with a 1.5-m telescope in June 1974 and June, July and August 1976. The resulting light curves, color curves and color excesses are interpreted in terms of a gas disk of electron density approximately 10 to the 12th/cu cm and radius approximately 20 solar radii surrounding the primary component, and a gas stream contributing to the 3.8-micron radiation between the components.
