Description


We present a comprehensive analysis, including B and V light curves and 11 high-resolution spectra, to verify the orbital period and determine parameters. The spectroscopic and photometric analyses agree on a period of 0.896640+/-0.000007d. We determine a mass of 9.0+/-0.6M_{sun}_ for each component and temperatures of 28000+/-2000K. Both values are consistent with the spectral type B1V. The two stars are overfilling their respective Roche lobes, sharing a common envelope, and therefore the orbit is synchronised and circularised. Thetwo stars are in a very advanced stage of interaction, with their extreme physical similarity likely due to the common envelope. The expected evolution of such a system will very probably lead to a merger while still on the main sequence.
