V1007 Sco, O-Type Binaries, Eccentric

Scientific paper

Improved orbital and physical parameters of the eccentric O-type system V1007 Sco (P=5.8 days) are presented. UBV light curves obtained over a period of 12 years were analyzed with a Wilson-Devinney-based solution code. Setting off from a set of parameters derived from spectroscopic investigations a consistent photometric solution was achieved. In accordance with the spectroscopic findings the eccentricity was determined as e=0.128 and the apsidal motion with a spectroscopic period of about 150 days was confirmed.
