SELF-MICROLENSING IN COMPACT BINARY-SYSTEMS

The signature of the self-microlensing in compact binaries (white dwar fs, neutron stars and black holes) is a flare with the characteristic time of typically a few minutes. The probability of detecting these mi crolensing events can be as high as 1/50 for a photometric accuracy of Delta m = 0.01 in magnitude. The discovery of the self-microlensing b y binaries would furnish an additional way to find the masses of the l ens and the companion, and will be promising for the searches of black holes.
