Binary and Multiple O-Type Stars in the Cas OB6 Association
Todd C. Hillwig, Douglas R. Gies, William G. Bagnuolo +3
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 binar…

Stellar Rotation in Young Clusters. II. Evolution of Stellar Rotation and Surface Helium Abundance
W. Huang, D. R. Gies
We derive the effective temperatures and gravities of 461 OB stars in 19 young clusters by fitting the H-gamma profile in their spectra. We use synthetic model profiles for rotatin…

Stellar Rotation in Young Clusters. I. Evolution of Projected Rotational Velocity Distributions
Wenjin Huang, Douglas R. Gies
Open clusters offer us the means to study stellar properties in samples with well-defined ages and initial chemical composition. Here we present a survey of projected rotational ve…
