Apsidal motion in massive close binary systems - I: HD 165052, an extreme case?

We present a new set of radial velocity measurements of the spectroscopic binary HD 165052 obtained by disentangling high-resolution optical spectra. The longitude of the periastron (ω = 60 ± 2°) shows a variation with respect to previous studies. We have determined the apsidal motion rate of the sy...
