Abstract:
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 of the system and thus the absolute masses of both
components. We observed photometrically 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 spectroscopic period of 3.16412-days,
presenting two minima corresponding to the conjunctions of the binary
components. Numerical models fitted to the light curve indicate an
orbital inclination of about 44deg, and masses of 53M_sun_ and
42M_sun_ for the O- and WN-type components, respectively.
