Abstract:
We present the catalog of 2580 eclipsing binary stars detected in 4.6
square degree area of the central parts of the Large Magellanic Cloud.
The photometric data were collected during the second phase of the
OGLE microlensing search from 1997 to 2000. The eclipsing objects were
selected with the automatic search algorithm based on an artificial
neural network. Basic statistics of eclipsing stars are presented.
Also, the list of 36 candidates of detached eclipsing binaries for
spectroscopic study and for precise LMC distance determination is
provided. The full catalog is accessible from the OGLE Internet
archive.
