The early-type strong emission-line supergiants of the Magellanic Clouds : a spectroscopic zoology.

Shore, S. N.; Sanduleak, N.

The results of a spectroscopic survey of 21 early-type extreme emission line supergiants of the Large and Small Magellanic Clouds using IUE and optical spectra are presented. The combined observations are discussed and the literature on each star in the sample is summarized. The classification procedures and the methods by which effective temperat…

The S201 far-ultraviolet imaging survey. III. A field in Sagttarius.

Page, T.; Carruthers, G. R.

Far-ultraviolet imagery of a 20 deg diameter field in Sagittarius, centered near (1950) R.A. 18 h 34 m, decl. -30 deg 25 arcmin, was obtained by the S201 far-ultraviolet camera during the Apollo 16 mission. In a 10-minute exposure covering the 1250-1600 A wavelength range, 1034 star images are detectable, with a limiting ultraviolet magnitude of a…

Comparison of variations in the visible and ultraviolet spectra of a Centauri.

Fahey, R. P.

Equivalent-width and central depth measurements of some ultraviolet absorption lines from the spectrum of the He I spectrum variable star a Cen (HD 125823) are presented. The measurements are from 53 short-wavelength and 52 long-wavelength, high-resolution spectrographs taken with the IUE satellite over a 25^d period during 1978 July and…
