Radial Velocities of Six OB Stars (2007)

Boyajian, T. S., Gies, D. R., Baines, E. K., Barai, P., Grundstrom, E. D., McSwain, M. V., ...

We present new results from a radial velocity study of six bright OB stars with little or no prior measurements. One of these, HD 45314, may be a long-period binary, but the velocity variations of...

The Long Period, Massive Binaries HD 37366 and HD 54662: Potential Targets for Long Baseline Optical Interferometry (2007)

Boyajian, T. S., Gies, D. R., Dunn, J. P., Farrington, C. D., Grundstrom, E. D., Huang, W., ...

We present the results from an optical spectroscopic analysis of the massive stars HD 37366 and HD 54662. We find that HD 37366 is a double-lined spectroscopic binary with a period of 31.8187 +/-...

Joint H-alpha and X-Ray Observations of Massive X-Ray Binaries. III. The Be X-ray Binaries HDE 245770 = A 0535+26 and X Persei (2007)

Grundstrom, E. D., Boyajian, T. S., Finch, C., Gies, D. R., Huang, W., McSwain, M. V., ...

We present results from an H-alpha monitoring campaign of the Be X-ray binary systems HDE 245770 = A 0535+26 and X Per. We use the H-alpha equivalent widths together with adopted values of the Be...

The B-Supergiant Components of the Double-Lined Binary HD1383 (2006)

Boyajian, T. S., Gies, D. R., Helsel, M. E., Kaye, A. B., McSwain, M. V., Riddle, R. L., ...

We present new results from a study of high quality, red spectra of the massive binary star system HD 1383 (B0.5 Ib + B0.5 Ib). We determined radial velocities and revised orbital elements (P =...

The Massive Runaway Stars HD 14633 and HD 15137 (2004)

Boyajian, T. S., Beaulieu, T. D., Gies, D. R., Grundstrom, E., Huang, W., McSwain, M. V., ...

We present results from a radial velocity study of two runaway O-type stars, HD 14633 (ON8.5 V) and HD 15137 (O9.5 III(n)). We find that HD 14633 is a single-lined spectroscopic binary with an...
