摘要：
Despite the large impact very massive stars (> 30 M-circle dot) have in astrophysics, their fundamental parameters remain uncertain. I present results of a survey aiming to characterize the most massive stars in the Magellanic Clouds. The survey targets the brightest, blue, eclipsing binaries discovered by the OGLE microlensing survey, for which masses and radii are measured to 50%. Such precise data are rare and provide constraints for theories of massive star formation and evolution at low metallicities.
