Scientific paper

Microlensing distant stars by non-compact objects such as neutralino stars is considered. Recently Gurevich and Zybin considered the objects as microlenses. Using the non-singular density distribution we analyze microlensing by non-compact objects. We obtain the analytical solutions of the gravitational lens equation and the analytical expression for the amplification factor of the gravitational lens. We show that using the model of microlensing by non-compact objects it is possible to interpret microlensing event candidates having two typical maximums of light curves which are usually interpreted as binary microlenses. .
