Abstract
A theory of microlensing by nonbaryonic bodies is developed. The characteristic features of lensing by noncompact transparent objects with a singular density distribution are investigated. The conditions under which additional peaks appear in the brilliance curve and the characteristics of these peaks are determined. The effect of a compact baryonic nucleus on the brilliance curve is studied.
