Spectroscopic binary orbits from ultraviolet radial velocities. Paper 9: Y Cygni (HD 198846)

Stickland, D. J.; Lloyd, C.; Pachoulakis, I. +2 more

The paper presents spectroscopic binary orbits of Y Cygni obtained from the results of a three-day observations (covering 16 hours of each day) of this eclipsing binary, made by the IUE satellite at the end of May 1990. Full cross-correlation reduction of high-dispersion spectra secured over the three days allowed the production of an orbital solu…

Spectroscopic binary orbits from ultraviolet radial velocities. Paper 10: CW Cephei (HD 218066)

Stickland, D. J.; Koch, R. H.; Pfeiffer, R. J.

Observations of CW Cephei were carried out repeatedly in the course of three days in December 1991, using the high-resolution, short-wavelength spectrograph of IUE, with an additional spectrum taken on February 6, 1992. The paper presents a log of these observations, which represent the only high-resolution observations of this star in the archive…
