HD 192641 and HD 193077: two single, hydrogen-rich Wolf-Rayets
Description
For the past two observing seasons the author has obtained coude spectrograms (10 A/mm) at KPNO of the northern WR stars with absorption lines but no orbit solutions. The naive motivation for this project was to determine more orbits and hence masses, since the masses of WR stars are poorly determined. The first two stars studied have been HD 192641 (WC 7) and HD 193077 (WN 5). Both show the upper Balmer lines in absorption plus the emission lines appropriate to their subclasses. Neither showed any trace of radial velocity variations. The author discusses the implications of this result. (Auth.)
