| Abstract: |
The RR Lyrae in the bulge have been proposed to be the oldest populations in the Milky Way, tracers of how the galaxy formed. We study here the distribution of ~1600 bulge RR Lyrae stars found by the MACHO Project. The RR Lyrae with Galactocentric radius 0.4<R<3 kpc show a density law that is consistent with the extension of the metal-poor stellar halo present in the outer regions of the Milky Way. |
