The Orbits of the Gamma-ray Binaries LS I +61 303 and LS 5039 (2009)
Aragona, Christina, McSwain, M. Virginia, Grundstrom, Erika D., Marsh, Amber N., Roettenbacher, Rachael M., Hessler, Katelyn M., ...
LS I +61 303 and LS 5039 are two of only a handful of known high mass X-ray binaries (HMXBs) that exhibit very high energy emission in the MeV-TeV range, and these "gamma-ray binaries" are of renewed...
Angular Diameters of the Hyades Giants Measured with the CHARA Array (2008)
Boyajian, Tabetha S., McAlister, Harold A., Cantrell, Justin R., Gies, Douglas R., Brummelaar, Theo A. Ten, Farrington, Chris, ...
We present angular diameters of the Hyades giants, gamma, delta^1, epsilon, and theta^1 Tau from interferometric measurements with the CHARA Array. Our errors in the limb-darkened angular diameters...
Raghavan, Deepak, McAlister, Harold A., Torres, Guillermo, Latham, David W., Mason, Brian D., Boyajian, Tabetha S., ...
We present an updated spectroscopic orbit and a new visual orbit for the double-lined spectroscopic binary \sigma^2 Coronae Borealis based on radial velocity measurements at the Oak Ridge Observatory...
Boyajian, Tabetha S., McAlister, Harold A., Baines, Ellyn K., Gies, Douglas R., Henry, Todd, Jao, Wei-Chun, ...
Using the longest baselines of the CHARA Array, we have measured the angular diameter of the G5 V subdwarf $\mu$ Cas A, the first such determination for a halo population star. We compare this result...
Runaway Massive Binaries and Cluster Ejection Scenarios (2006)
McSwain, M. Virginia, Ransom, Scott M., Boyajian, Tabetha S., Grundstrom, Erika D., Roberts, Mallory S. E.
The production of runaway massive binaries offers key insights into the evolution of close binary stars and open clusters. The stars HD 14633 and HD 15137 are rare examples of such runaway systems,...
A Spectroscopic Study of Field and Runaway OB Stars (2006)
McSwain, M. Virginia, Boyajian, Tabetha S., Grundstrom, Erika D., Gies, Douglas R.
Identifying binaries among runaway O- and B-type stars offers valuable insight into the evolution of open clusters and close binary stars. Here we present a spectroscopic investigation of 12 known or...
