Toward Early-type Eclipsing Binaries as Extragalactic Milestones. III. Physical Properties of the O-type Eclipsing Binary OGLE LMC-ECL-21568 in a Quadruple System ,

We present the results from a complex study of an eclipsing O-type binary (Aa+Ab) with the orbital period of  P _A = 3.2254367 days that forms part of a higher-order multiple system in a configuration of (A+B)+C. We derived masses of the Aa+Ab binary of  M _1 = 19.02 ± 0.12 and M _2 = 17.50 ± 0.13 M...
