Abstract:
We present the results of time-resolved spectroscopy of 13 O-type
stars in the Cas OB6 stellar association. We conducted a survey for
radial velocity variability in search of binary systems, which are
expected to be plentiful in young OB associations.
Description:
The blue spectra were obtained with the Ritchey-Chretien spectrograph
at the Mayall 4m telescope at KPNO from 2003 September 30 through 2003
October 4. We also obtained an additional 32 spectra of HD 17505A with
the KPNO 0.9m coude feed telescope in runs in 2000 October and
December.
