摘要：

A detailed theory is developed for microlensing by non-compact dark matter objects - the neutralino stars - predicted by Gurevich and Zybin [Phys. Lett. A 208 (1995) 276]. It is shown that microlensing observations are in agreement with the theory. A method allowing one to test the presence of non-compact objects is pointed out, Among the available observational data, one case is presented where the difference between the microlensing by non-compact and compact objects is clearly seen. The size of the object determined from these observations is R(x) similar or equal to 10(14) cm.
