Variability of Be Stars in Southern Open Clusters
M. Virginia McSwain, Wenjin Huang, Douglas R. Gies
We recently discovered a large number of highly active Be stars in the open cluster NGC 3766, making it an excellent location to study the formation mechanism of Be star disks. To…
A FUSE Survey of the Rotation Rates of Very Massive Stars in the Small and Large Magellanic Clouds
Laura R. Penny, Douglas R. Gies
We present projected rotational velocity values for 97 Galactic, 55 SMC, and 106 LMC O-B type stars from archival FUSE observations. The evolved and unevolved samples from each env…
The High Angular Resolution Multiplicity of Massive Stars
Brian D. Mason, William I. Hartkopf, Douglas R. Gies +2
We present the results of a speckle interferometric survey of Galactic massive stars that complements and expands upon a similar survey made over a decade ago. The speckle observat…
First Resolved Images of the Eclipsing and Interacting Binary Beta Lyrae
M. Zhao, D. Gies, J. D. Monnier +12
We present the first resolved images of the eclipsing binary Beta Lyrae, obtained with the CHARA Array interferometer and the MIRC combiner in the H band. The images clearly show t…
Detection of a Hot Subdwarf Companion to the Be Star FY Canis Majoris
Geraldine J. Peters, Douglas R. Gies, Erika D. Grundstrom +1
The rapid rotation of Be stars may be caused in some cases by past mass and angular momentum accretion in an interacting binary in which the mass donor is currently viewed as a sma…
Angular Diameters of the G Subdwarf Cassiopeiae A and the K Dwarfs Draconis and HR 511 from Interferometric Measurements with the CHARA Array
Tabetha S. Boyajian, Harold A. McAlister, Ellyn K. Baines +13
Using the longest baselines of the CHARA Array, we have measured the angular diameter of the G5 V subdwarf Cas A, the first such determination for a halo population star. We co…
