Abstract

The OGLE project is a long-term large-scale variability sky survey that monitors about 1.3 billion stars of the Milky Way and Magellanic System. Our recent searches for eclipsing binary stars in the OGLE-III Galactic bulge fields have led to the detection of nearly 23,000 binaries with orbital periods shorter than 4 days. In this contribution, we present the results of an analysis of period changes in this sample of binaries based on two decades of the OGLE observations.
