    New and revised parameters for several southern OB binaries

  • Original language description

    Using ESO FEROS archive spectra of several southern OB-type binaries, we derived periods for three SB2 spectroscopic binaries, HD 97166, HD 115455, and HD 123590, and two SB1 systems, HD 130298 and HD 163892. It was also possible to use new FEROS spectrato improve the parameters of the known binaries, KX Vel and HD 167263. For KX Vel, we determined a dynamic mass of the primary of 16.8 M-circle dot, while the evolutionary model suggests a higher value of 20.2 M-circle dot. We derived an improved periodfor HD 167263, and in its spectra, we recognized contributions of both of its interferometric components.
