摘要: If the dark matter in Galactic halo consists of compact objects 10 −6 -10 2 M ⊙ mass range, it can be detected as gravitationally microlenses stars neighboring galaxies and bulge. Though extremely rare, microlensing has several powerful signatures: light curves follow a well-known function, are time symmetric, same all filter bands. These signatures, however, may lost if source star is member binary system. Since most are, fact, members binaries, true events rejected background
