The double-line spectroscopic binary HD 159176.
Abstract
From conde' observations at Kitt Peak and Cerro Tololo we derive the orbital elements of the system HD 159176. Both stars are practically identical O7 stars, each already evolved from the ZAMS. The close separation, probable synchronous rotation, and near filling of their Roche lobes suggest photometric variability will be observable. Eclipses are unlikely. Key words: binary stars - spectroscopic binaries - orbital elements
