Résumé :

The Optical Gravitational Lensing Experiment (OGLE) collaboration makes routine microlensing survey observations of many square degrees towards the Galactic Centre. A by-product of the second evolution of this survey (OGLE-II) was a proper motion catalogue of 5 x 105 stars. This talk will present the results of a comparision of observed proper motion dispersions of stars in the Galactic Centre to a state-of-the-art particle simulation of the Galaxy.
