Resumen:
We present a simultaneous spectroscopic-photometric analysis of five eclipsing binaries in the LMC. Using spectroscopic observations obtained with VLT+UVES and MagellanII+MIKE and photometric data from the MACHO and OGLE databases we determine absolute stellar parameters. The object MACHO82.9010.36 is a spectroscopic triple system. The binaries 78.6708.115 and 82.9130.25 are eccentric systems showing apsidal motion due to tidal forces. The apsidal motion rate is used to obtain information about the internal mass distribution of these stars.
