Abstract:
Having obtained new series of electronic spectra and UBV photometry of
V1007 Sco, we analysed these data in an effort to check whether the
observed properties of V1007 Sco indeed disagree with the prediction
of stellar evolutionary models. We briefly analysed data for a few
other binaries in NGC 6231, too.
Spectral reductions were carried out with the MIDAS program,
photometry reduced using the HEC22 program, the orbital elements were
derived with the FOTEL program and the final solutions obtained with
the program PHOEBE.
