The structure of the Large Magellanic Cloud from hot binary stars and Classical Cepheids

We present the results of analysis of 1764 eclipsing binary stars (EBs) in the Large Magellanic Cloud (LMC) contaminating the sample of candidate Classical Cepheids (CCs) from the EROS-2 survey. These binaries have the same periods and luminosities as Classical Cepheids, but their colors are bluer. These EBs contain hot massive Main Sequence components and could be used as tracers of regions of recent star formation activity.
