Orbital solution for the MACHO*05:34:41.3-69:31:39 O3If*+O6:V eclipsing binary system in the Large Magellanic Cloud.


Abstract (from CDS):

An orbital solution for the MACHO*05:34:41.3-69:31:39 eclipsing binary system is presented, based on the published light curve and spectral data obtained with the 2.15-m telescope at CASLEO. Based on these spectroscopic observations, the binary components of this system were classified as O3If* and O6:V respectively. The radial velocity data along with the published light curve were analysed with the Wilson-Devinney code to derive the following masses and radii for the components of this system: {formmu1} {formmu2} {formmu3} and {formmu4} The solution shows that the system is in overcontact, as one would expect from the derived masses and the very short orbital period (∼1.4d).
