Young, P. ; Schneider, D. P. ; Shectman, S. A. Abstract Emission lines in the region 4045-4945 A are observed for nearly two complete orbits of Stepanyan's star. Three eclipses of the system are observed at 2.5 A spectral and 100 second time resolution. The spectral region 6800-9200 A is observed for one complete orbit at 10 A resolution. No absorption lines or bands from a red dwarf are observed, even at mid-eclipse. Absorption lines of O I are seen in the infrared, which are strongest at phases 0.4-0.5 and are invisible at mid-eclipse.
