A very massive spectroscopic binary in the LH 54 OB association in the LMC

Abstract

We announce the discovery of a new early-type, double-lined spectroscopic binary in the LH 54 OB association in the LMC. We present a V light curve and radial velocities. We investigate the possible configurations of the system, concluding that it probably contains the most massive star measured at the present, with a mass (in solar units) of the order of 100, while its companion has approximately 50.
