Scientific paper

We present a new V light curve of the early type Magellanic eclipsing binary Sk-67°105, based on charge-coupled device images obtained at CASLEO. We perform an analysis of our data, together with published radial velocities, deriving the following masses and radii: M1= 48.3 Msolar, R1= 16.9 Rsolar for the O4f component and M2= 31.4 Msolar, R2= 13.8 Rsolar for the O6 component. We found that this system is the brightest member of a tight star cluster, belonging to an OB association.
