EROS CATALOG OF ECLIPSING BINARY STARS IN THE BAR OF THE LARGE MAGELLANIC CLOUD

We present a catalogue of 79 certain or probable eclipsing binary star s located in the bar of the Large Magellanic Cloud. The stars were ide ntified from the French EROS microlensing project's 1991-92 season of CCD observations using Grison's (1994) period-searching procedure, whi ch incorporates higher harmonics into the periodogram search of photom etric time sequences. Only one of the systems was previously identifie d and our catalogue doubles the number of known eclipsing binaries in the LMC. The systems mostly range from 15(th) to 18(th) mag., exhibit blue colours and have periods less than 10 days. At least ten systems are eccentric. Coordinates and ephemerides are presented, as well as i dentification charts and light curves at 490 and 670 nm. The catalogue and light curves are available electronically from the CDS, Strasbour g.
