Abstract
The microlensing objects, Machos, recently observed in the halo of our Galaxy, can be interpreted as dense neutralino objects, neutralino st ars, produced by the gravitational instability of neutralino gas. Taki ng the mass and radius of these objects from microlensing observations we calculated the diffuse gamma-ray flux produced in neutralino-neutr alino annihilation inside the objects. The resulting flux is many orde rs of magnitude higher than the observed one.
