Resumen

We present the preliminary results of our astrometric study of stellar motions along the lines of sight of the Magellanic Clouds and the Galactic bulge. Using 5 years of MACHO project point-spread function photometry, we find that we can easily select stars with proper motions of 0″.03 yr -1 from these very dense fields, using the characteristic shapes of their light curves. By performing astrometry on photometrically selected, candidate, high proper motion (HPM) stars in 50 deg 2 , we have discovered 154 new HPM stars from ∼55 million stars monitored by the MACHO project. These new objects have proper motions as high as 0″.5 yr -1 , brightnesses ranging from V ∼ 19 to V - 19, and V - R colors between 0.3 and 1.45.
