Self-Microlensing in Compact Binary Systems

The signature of the self-microlensing in compact binaries (white dwarfs, neutron stars and black holes) is a flare with the characteristic time of typically a few minutes. The probability of detecting these microlensing events can be as high as $1/50$ for a flux sensitivity of $Δm=0.01$ in magnitude. The discovery of the self-microlensing by binaries would furnish an additional way to find the masses of the lens and the companion and will be promising for the searches of black holes.
