Abstract

Microlensing of background stars by neutralino stars, which were proposed in a recent work by Gurevich and Zybin as the component making the main contribution to the dark matter, is studied. The optics of such a gravitational microlens—the equation of the lens, the solution of this equation, the intensification of images, and the critical and caustic curves—are analyzed in detail in a quite simple approximation. A set of different values of the parameters of the problem is studied.
