Dynamical Masses for the Large Magellanic Cloud Massive Binary System [L72] LH 54-425
S. J. Williams, D. R. Gies, T. J. Henry +8
We present results from an optical spectroscopic investigation of the massive binary system [L72] LH~54-425 in the LH 54 OB association in the Large Magellanic Cloud. We revise the…
Effects of Metallicity on the Rotation Rates of Massive Stars
Laura R. Penny, Amanda J. Sprague, George Seago +1
Recent theoretical predictions for low metallicity massive stars predict that these stars should have drastically reduced equatorial winds (mass loss) while on the main sequence, a…
Tomographic Separation of Composite Spectra. X. The Massive Close Binary HD 101131
D. R. Gies, L. R. Penny, P. Mayer +2
We present the first orbital elements for the massive close binary, HD 101131, one of the brightest objects in the young, open cluster, IC 2944. This system is a double-lined spect…
Tomographic Separation of Composite Spectra. IX. The Massive Close Binary HD 115071
L. R. Penny, D. R. Gies, J. H. Wise +2
We present the first orbital elements for the massive close binary, HD 115071, a double-lined spectroscopic binary in a circular orbit with a period of 2.73135 +/- 0.00003 days. Th…
Tomographic Separation of Composite Spectra. VIII. The Physical Properties of the Massive Compact Binary in the Triple Star System HD 36486 (delta Orionis A)
James A. Harvin, Douglas R. Gies, William G. Bagnuolo +2
Double-lined spectroscopic orbital elements have recently been found for the central binary in the massive triple, delta Orionis A based on radial velocities from cross-correlation…
Orbits of Four Very Massive Binaries in the R136 Cluster
Philip Massey, Laura R. Penny, Julia Vukovich
We present radial velocity and photometry for four early-type, massive double-lined spectroscopic binaries in the R136 cluster. Three of these systems are eclipsing, allowing orbit…
