Scientific paper

The semi-detached eclipsing binary system BP Muscae has been analysed using the Wilson-Devinney program. Light curves have been obtained in the GENEVA 7-colour photometric system, and radial velocity curves for both components have been measured with the spectrograph CORALIE. The physical and orbital parameters have been determined through a self-consistent simultaneous solution of light curves in seven colours and of the radial velocity curves of both components. The absolute elements of the components are, for the primary (mass gainer), M1 = 2.40 +/- 0.01 Msun, R1 = 2.64 +/- 0.01 Rsun, Mbol_1 = 0.66 +/- 0.04, Teff_1 = 9180 +/- 90 K, and for the secondary (mass loser), M2 = 0.68 +/- 0.01 Msun, R2 = 3.76 Rsun, Mbol_2 = 2.40 +/- 0.08, Teff_2 = 5160 +/- 90 K. The semi-major axis A of the relative orbit is 13.617 +/- 0.019 Rsun. The spectral type of the components are A0.5/1.5 V (primary) and about G5 III. The distance to BP Mus is evaluated as 562 +/- 17 pc, and the colour excess E[B2-V1] as 0.220 +/- 0.014.
Based on observations collected at the Swiss 70 cm and 120 cm telescopes at the European Southern Observatory (La Silla, Chile).
