The eclipsing binary HD 92024 : 'Getting the orbit'
HD92024 is an SB1 eclipsing binary system with a Beta Cephei star as primary component. We report on the progress of a combined photometric and spectroscopic investigation of this binary, being the only known one of its type in the southern hemisphere. Pulsating components of spectroscopic binaries often introduce substantial line-profile variations in the spectra, which hampers the determination of orbital radial-velocity amplitudes and thus the stellar masses. Here, in order to minimise the bias from line-profile variations on the orbital RVs, we use selected matched-profile RV differences to derive the orbital paramterers. The method is compared to straightforward cross-correlations of the spectra with an average spectrum.
