We present results from a study of the orbits of eclipsing binary stars (EBs)in the Magellanic Clouds. The samples comprise 4510 EBs found in the LargeMagellanic Cloud (LMC) by the MACHO project, 2474 LMC EBs found by the OGLE-IIproject (of which 1182 are also in the MACHO sample), 1380 in the SmallMagellanic Cloud (SMC) found by the MACHO project, and 1317 SMC EBs found bythe OGLE-II project (of which 677 are also in the MACHO sample); we alsoconsider the EROS sample of 79 EBs in the bar of the LMC. Statistics of thephase differences between primary and secondary minima allow us to infer thestatistics of orbital eccentricities within these samples. We confirm thewell-known absence of eccentric orbit in close binary stars. We also findevidence for rapid circularization in longer period systems when one memberevolves beyond the main sequence, as also found by previous studies.
