MAIN SCIENTIFIC RESULTS
of the OGLE PROJECT

OGLE-I

• discovery of the first microlensing events toward the Galactic bulge (Udalski et al. 1993)

• first determination of the optical depth for microlensing toward the Galactic bulge (Udalski et al. 1994a)

• discovery of the first microlensing by a binary object - OGLE-BUL-7 (Udalski et al. 1994b)

• first system of detection of microlensing events in progress ( Early Warning System, EWS, Udalski et al. 1994c)

• the Galactic structure analysis - evidence for existence of a bar in the Galaxy (Stanek et al. 1996)

• publication of extinction maps towards the Galactic Bulge (Stanek 1996)

• variable stars search in the direction of the Galactic center: "Catalog of Periodic Variable Stars in the Galactic Center" (Udalski et al. 1997) including 2861 objects

• photometry of globular clusters - discovery of numerous detached eclipsing binaries in omega Cen and 47 Tuc (Kaluzny et al. 1996)

• photometry of dwarf galaxies in Sculptor (Kaluzny et al. 1995) and Sagittarius (Mateo et al. 1996)
