Microlensing of disk sources

Abstract

We analyse the effects on the predictions for the microlensing searches toward the Galactic bulge coming from the fact that not all the stars monitored belong to the bulge itself, but that a non--negligible fraction of them actually are in the Galactic disk. The different distribution and motions of these disk stars make their associated microlensing rates and event duration distributions to be quite different from those of the bulge stars. We discuss the uncertainties in these predictions associated to the modeling of the Galactic components and the main implications resulting from the inclusion of this second source population.
