Abstract

H-band imaging of the central region of the Local Group galaxy M33 reveals a bulge with effective radius 0.5 kpc. The brightest bulge stars are resolved. After subtraction of disk contamination, we conclude that the brightest M33 bulge stars are substantially brighter than the brightest stars found in the Milky Way bulge. This fact suggests that the star formation histories of all bulges are not the same; specifically, M33's bulge underwent a star formation episode less than 1 Gyr ago.
