Abstract: We report early results of a stellar population study based on color gradients for a large sample of nearby S0 galaxies. The color gradients are constructed from near-IR and optical images. IR images were collected with ULBCam at the University of Hawaii 2.2-m telescope. Optical data are taken from the Sloan Digital Sky Survey. U-band data were obtained from the SOAR Optical Imager, along with B and R-band data. Surface brightness profiles (out to 3 − 4 disk scale lengths) were extracted from the images. Galaxy colors are compared to stellar population synthesis models, revealing radial trends of ages and metallicities of stellar populations in the bulge and disk.
