The O4f + O6V eclipsing binary system Sk-67°105 in the Large Magellanic Cloud.

OSTROV P.G. and LAPASSET E.

Abstract (from CDS):

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 M☉, R1= 16.9 R☉for the O4f component and M2= 31.4 M☉, R2= 13.8 R☉for the O6 component. We found that this system is the brightest member of a tight star cluster, belonging to an OB association.
