Resumen:
WR 29 is a known WN7h+O double-lined binary system with a rather short period(3.164 days). We search for light variations to determine the inclination ofthe system and thus the absolute masses of both components. We observedphotometrically the field of WR 29 between December, 2002 and February, 2006.We find that the V light of WR 29 varies in phase with the spectroscopicperiod of 3.16412 days, presenting two minima corresponding to theconjunctions of the binary components. Numerical models fitted to the lightcurve indicate an orbital inclination of about 44o, and masses of 53 Msun and42 Msun for the O- and WN-type components, respectively.
