摘要

We proposed to obtain IUE spectra of a number of very young stars in the Taurus-Auriga dark clouds. We were awarded eight US1 shifts of IUE observing time during the sixteenth episode. We obtained 10 low-dispersion spectra for seven different young stars in the Taurus-Auriga dark clouds during our IUE shifts. To acquire the data for analysis of wind variability in Be stars, five US2 shifts on IUE were used. Thirty-three high dispersion spectra were acquired, primarily of Be stars which had been observed only once early in the mission. The third program's goal was to obtain sufficiently good new exposures to permit definitive analysis for the temperatures, interstellar reddening, and luminosity ratios in several binary star systems. Monitoring observations of the four target Be stars in the final program were conducted simultaneously with the IUE satellite and with the McMath-Pierce telescope on Kitt Peak in November, 1993.
