Stellar Rotation in Field and Cluster B-Stars
Wenjin Huang, Douglas R. Gies
We present the results of a spectroscopic investigation of 108 nearby field B-stars. We derive their key stellar parameters, , , , and $\log g_{\rm p…
Stellar Wind Variations During the X-ray High and Low States of Cygnus X-1
D. R. Gies, C. T. Bolton, R. M. Blake +10
We present results from Hubble Space Telescope UV spectroscopy of the massive X-ray binary system, HD226868 = Cyg X-1. The spectra were obtained at both orbital conjunction phases…
Joint H-alpha and X-ray Observations of Massive X-ray Binaries. I. The B-Supergiant System LS I +65 010 = 2S 0114+650
E. D. Grundstrom, J. L. Blair, D. R. Gies +8
We report on a three year spectroscopic monitoring program of the H-alpha emission in the massive X-ray binary LS I +65 010 = 2S 0114+650, which consists of a B-supergiant and a sl…
Joint H-alpha and X-Ray Observations of Massive X-Ray Binaries. II. The Be X-ray Binary and Microquasar LS I +61 303
E. D. Grundstrom, S. M. Caballero-Nieves, D. R. Gies +6
We present the results of an H-alpha monitoring campaign on the BeXRB and microquasar system LS I +61 303. We use radial velocity measurements of HeI lines in our spectra to re-eva…
Mass and Angular Momentum Transfer in the Massive Algol Binary RY Persei
P. Barai, D. R. Gies, E. Choi +12
We present an investigation of H-alpha emission line variations observed in the massive Algol binary, RY Per. We give new radial velocity data for the secondary based upon our opti…
The N Enrichment and Supernova Ejection of the Runaway Microquasar LS 5039
M. V. McSwain, D. R. Gies, W. Huang +3
We present an investigation of new optical and ultraviolet spectra of the mass donor star in the massive X-ray binary LS 5039. The optical band spectral line strengths indicate tha…
