Scientific paper

A definitive set of orbital and physical parameters of the binary system V 1007 Sco is presented. Both stars are classified as O7 giants. Light and RV curves were simultaneously analyzed with PHOEBE, a modern WD-based solution code. A statistical approach yielded realistic error estimates. Orbital eccentricity is 0.12 with an apsidal motion period of 112 years.
