MICROLENSING RESULTS FROM EROS

    Abstract:

    We present the results of the EROS-2 search for microlensing of stars in the Magellanic clouds and in the Milky-Way plane. More than hundred million of stars were monitored over a period of about 7 years. Hundreds of microlensing candidates have been found in the galactic plane, but only one was found towards the subsample of bright –well measured– Magellanic stars. This result implies that massive compact halo objects (machos) in the mass range 10−7M⊙ < M < 5M⊙ are ruled out as a major component of the Milky Way Halo. The optical depth estimates and the event duration distributions comply with the simple standard Milky-Way model.
